Don G. has been in contact with me and has an M8 that is very slightly shorter than the others. Is there anyone who has an idea about this? Jim, I suggested he contact you.

Well, being in California, I had to get rid of mine years ago. But I have an old Ordanace Catalog ORD 9 SNL B-39
It has pictures and a measurement scale in it.

In the margins I wrote:

U.S. CARBINE GRENADE LAUNCHER M8
RELIANCE MACHINE & TOOL CO.
Measurements: OL: 15.2CM 6" 12 oz.

Years ago I carefully took out the staples and made a few copies. I found some of those last night, but now I can't find the original. I guess I really put it away for safe keeping. "8 1/2" X 5 1/2" 28 pages with nomenclature and list of parts.

This is seven of the pages from old photos.

I find it amazing what you guys have tucked away. Who would have thought to keep an old pam like that.

I have a smaller copy of the ORD 9 SNL B-39 too, my was sent to me from the M1 Carbine Club in the late 1980's as a gift

I copied mine back then and send them, one for each member at the time, to the club. Same with the serial number cards.
