Type V slide question

[imarangemaster]

My 3.00 Mil Inland has a 11-43 barrel, so I am assuming a born on date of around 12-43 to 1-44. It has a Type V "PI" slide that Riesch says Inland started using around 5.0 Mil. Dave has a nearly identical 3.05 Mil Inland with the type V also, so I would agree with him that Inland was using the later slides by then. Probably an error on Riesch part from limited data to deal with.

Question one is: What date was the new change (Type V) slide introduced?
Question two is: Anyone else have a Type V slide on any Carbine with a BOD of around 1-44?

I think your barrel date is close to the receiver date. WB lists the type 5 slide as early in 1944 which could be very close to the range listed in Riesch. Inland was in the 4.9 million range in Feb.1944.

The first type 5' were used at inland by Oct. '43. I also have 979k with that slide and there are others reported in the CCNL's . The first of these slides have the later style cams but do not have the increased dwell time. There are visual differences in the type 5 or L379 slides.

My 4.927 (1-44 bbl) has the V slide, and I thought it was a later upgrade. Very interesting indeed.

Hey Dave,
Wasn't there a difference in the thickness of the rear wall on the 2 Type 5 Slides?

Thx,

I know I am late to the party, and just back from a 2 year hiatus (and back with new toys to share), but I bought a attic fresh 3.09 Inland tonight from a friend of a friend's brothers estate with a 12-43 barrel, appears to be a fully forgotten bring back, long and the short is it has that slide as well and my first thought was doesn't seem right, everything else on the gun is as expected. Oh it also has ink stamp in the barrel channel, kinda strange for a IO?

With all due respect, how do you know this is true? Without additional written documentation, if the Type V slide was first issued in early 1944 (or October 1943) then every carbine ever produced could presently be wearing a Type V replacement slide for 70 years. Is there any written record documentation as to precisely when Inland (or Winchester) started installing Type V slides? If so, why does WB claim early 1944, 2-4 months later? If the TYpe V slide was fully developed, approved and issued in October 1943, apparently as a design improvement, why did the government not require the other manufacturers to adopt the improved design over the next 6-7 months? I am no statistician and maybe my logic is not foolproof, but I would look for the most probable DOM period of the last existing 'nest' of unmolested Inlands still wearing original Type IV slides and, given the very high monthly production rate at Inland, I would assume that initial installation of the Type V slide was started within the previous month or so. If there is no official document (U.S., Inland and/or Winchester) existing to fix a date of initial production and/or installation of the Type V slide then as far as I am coincerned this question may never be answered positively. As for me, my gut says that Inland started installing the Type V slide in Febraury or March of 1944, too late in the contracts of the second, third and fourth wave contractors to warrant re-tooling for no more than two months production. I suspect the 1943 Inlands now wearing 'original' Type V slides are armory queens or rear end/stateside locker fillers that were switched out when a box of 'new and improved' Type V slides were received by the unit in 1944-45 - a whole lot easier than replacing rear sights and barrel bands. It would be interesting to hear when Winchester is believed to have first issued the Type V slide as it should logically have been about the same time. JMHO, but what do I know!!!

Early L-379's were used at the start Oct 43, but during transition Inland used both E and L 379 slides. It is clearly stated in the Carbine Clubs newsletter's 149 and 150. It would be interesting to know if part number 7160091 is stamped on the bottom of your slides!

[imarangemaster]

Well my 11-43 Inland, serial number 3002830, is 100% correct besides slide. Considering the info in the CC newsletter, and the others with un-messed with Inlands in the 10-43 to 1-44 date range, I don't think the assumption that the type Vs are original to this block is unreasonable. Inland using-up the on hand prior versions after implementation of the new slides would explain Type IV slides also being found in this period.

Hi Curt,

Welcome back, glad to see the early release program worked out for you !!

Overton used the Ink stamp in a Julian Dating Format using a 5 digit number.
Lets say your stock was built 24th day August 1943 converted to Julian would be 43 (year) 236 (236th day of the year)........................ 43236
When compared the ink used at Overton is a different color/shade than the color used by the Irwins.

BTW,
My understanding is that the Number Stamps found in Irwin made stocks for SG, S'G'/IP were not a dating system but a possible inspection/shift/station/ tracking number.


Later Buddy,
