This should clear up a lot of questions. Thanks.

Jim, would you say that the most commonly encountered slides are type 4 and 5? Seems that way to me.

Just thought I'd let everyone know that I'm the one who took the photos posted in this thread and posted them at the CMP forum CMP Forums - View Single Post - Slide Q in 2012.

I also posted this at the end of that post

I bought two slides just to make these pictures and put some time into taking and composing the shots so if you share them please give credit where credit is due. Thanks.

but maybe that was overlooked.

Very nice, but where is the National Postal Meter variant Type II with Type IV arm joint? Did this part have a part number (code?) designation? Also, do the E168 and E169 Type II slides differ only in the shape of the bolt cam recess? I can't see any other possible difference. Sorry, but I am not up to speed on the part number designations (i.e E168 - my improper nomenclature?).

A lot of people here refer to these part numbers but I know they are not the US ordinance drawing numbers so a brief expalnation of where these numbers (E168, etc.) originate would be appreciated. I know this is a rube question but if I don't ask I'll never learn. Thanks, ChipS

The slide classification comes from the Carbine Club. It isn't an official classification system but it is used by collectors. The criteria can be seen on the Carbine Club data sheet http://www.carbineclub.com/DataSheetrev31-1-11.pdf

First letter: early (E) or late (L) cam shape
First number: arm joint - type 1, 2, 3, 4
Second number: rear of slide box - type 5, 6, 7
Third number: internal cam cut shape - type 8, 9

Milsurp Collector:

Thank you very much for the explanation and the reference. I will now be better informed when parts are so described.

To the Forum, I apologize for cluttering this sticky thread. I failed to remember where I was when I posted the question. ChipS
