Hello! and some carbine questions

[jman1100ct]

Gentlemen,
First let me say "Hello" and compliment you on the nice forum, it is definately a source of detailed information. I have lurked for a while but felt it was time to ask a few questions as I have just purchased and received a couple Inland RG carbines. While I know a fair amount about many different types of firearms, the subtle differences in US martial arm manufacture are somewhat of a mystery to me, so I am hoping you gentlemen can give me an education!

Of the two Inland's I received, one of them has a 6 digit receiver (507,xxx) and looks to be rebarrelled with an underwood '44 barrel. The other is seven digit (3,196,xxx), it has SG marked on the left side of the reciever under the wood, and what I think is the original inland 12-43 barrel.

Here are my first two questions:

1. Could anyone tell me why they changed the design of the groove on the back of the receiver (the one that mates with the recoil lug). The 6 digit inland has a groove that runs about half the width of the receiver while the 7 digit's runs the width of the receiver.

2. I realize that these are mixmasters, so I don't expect the slides to be correct, however I do see a difference between the two. On the 7 digit, the part which overlaps the receiver ring juts out farther, and is more angled than on the 6 digit. None of my other carbines have a slide of this configuration, so I found it odd. It is marked on the bottom of the slide with what appears to be 3G.

Any insight you gentleman have would be appreciated! Hopefully I can post some pictures and I am sure I will have some more questions! Thank you!

The difference in the receivers is because they were made by different manufacturers. The slides are different because the one with the angled cam area is a later design.

Welcome jman1100ct,

Any help given here requires the opening poster to put pictures up of his carbine(s) in the near future. The sooner the better ;-)

Your correct that your 6 digit Inland has been re-barreled.
Your 3,196,xxx falls into this Inland serial number block...
2,912,520-3,212,519. The use of sub contracted receivers from Saginaw Steering Gear (SG) of Saginaw Michigan fell into this general area...
3,152,520-3,212,519. SG receivers show up on early Inlands also in the 700,000 to 940,000 range. Basically SG helping Inland keep up production.
Your Inland falls with in this block and came with a receiver made/supplied by SG. SG and receivers made by the sub contractor Auto Ordnance have a FULL SIZE REAR LOCKING TANG. Some receivers marked with a SI on the side have also been found with the full width rear tang.

A nice find on your part.

The Op slide you describe sounds like the later version. A late type V or VI slide has more forward of an angle where the bolt/cam area meet. This change to a more forward angle was to improve the ejection of a spent casing. This improved slide increased the time before contacting the bolt's lug....etc.

Look for other markings on your slide. The WWII issued slides that came in a Type V or VI were originally used on late Inland and Winchester carbines.
Inlands were marked...Type V- PI and PI with the part number 7160091. Type VI slides for Inland could be found marked PI and 7161843.
Winchester made slides,
Type V marked, W or W with the part number 7160091.
Type VI marked, W and or 7161843

Saginaw (SG) also supplied to Inland Type VI slides marked SG and or with the part number 7161843.

Any markings other than these may very well just be some type of inspection stamping.

The Type VI slides can be used in all carbines BUT must be used in the M2 to allow space for the disconnector lever.

Someone will be along shortly to cross my T's and dot my I's.

Welcome,

Brian,
I wish I could have been so short and to the point.
Would have saved me 20 minutes of one finger typing.
Well I guess two. I can use my thumb for the shift key.

Cheers

Thank you both for the information! Here is a photo album of pictures of the 7digit. I added comments to some of the pictures, hopefully they show up. If you see anything notable please point it out, I would appreciate it!

I looked for markings on the slide, but only found what I have pictured. If it is a Type V or VI slide is it too late for the serial number?

In the end, I intend on giving one of the two to a friend, who just wants a shooter, so I am trying to decide which to keep, and I may swap parts if I can make one or the other more "correct".

Ok, here are the pictures of the 6 digit. 6 Digit pictures by jma5000 - Photobucket

It's kind of interesting because of the poor parkerizing job (maybe its not even park). It appears anything covered by wood did not get a finish. Also, the inscription TE 5-71 is a mystery to me. The barrel is in great shape, not very much muzzle wear at all. No pictures of the wood for this one, because it is clearly italian replacement wood. Any info about the bolt or slide would be appreciated.

Thank you all for your time!

Looks like a rust patina found on late 1800 Winchester lever guns on that receiver. Or maybe some cosmolene staining? Hard to say.

7 digit,
Slide is PI Would have to see the right side of the arm joint where it meets the slide box to see if it's a Type V or VI.
Too late for a 3,1 mil.
Inland trigger housing Type III.
KR2 Type III hammer marked KR2 ....for late Rock Ola.
OI 1 Type II flat bolt for Inland.
Mag catch and safety.......post war.
Can't make out the marking in the slingwell.
Handguard is a Winchester.

6 digit,
Brown look is the patina found on original finishes. Old grease, cosmo that has dried.
Etched number on bolt top....maybe Austrian/Bavarian marking.
TE-5-71 (?) Maybe a inventory marking ?
Trigger housing with the oil / lube hole on left side. Looks to be a Type VI for the M2.
Does it have a detent on the upper magwall/rightside?

B/R Type III flat hammer...for Rock Olas.
If magcatch is marked EI or HI it's a Inland Type IV late war. 30 rd catch.
Circle S slide it Standard Products. Number on bottom is production code.
N 11...Type II flat bolt for National Postal Meter.

HTH

TE 5-71 is Toole Army Depot May 1971.

The B/R in a double box hammer isn't Rock-Ola, it is a WWII era replacement.

The CC marked magazine catch is also a WWII era replacement made by Commercial Controls.

The slide on the 3.1 mil is the correct type.
