Correction, if I found it at a gun show I would steal it for $35.

A replica KA-BAR won't fit an M8 scabbard even if dimensions are true. If I see a rubber M3 I'll remember this post.

That is a beautiful collection. The bayonet looks amazing mounted. That guy probably paid $35 for a cut down fighting knife. Here is mine, I have yet to find an original but when I do I couldn't bring myself to steel it for $35, unless it was up for auction. 

Ah I see, I'm looking for one that will fit, but thanks for sharing!

Ok great, thanks for the confirmation, very much appreciated. 

Being a junk collector is such fun! We all like looking at others junk collections! 

I get different opinions. Some say the regiment and company numbers were attached and some say they were separate from the swords.    For an 1870s cavalry's regiment  What exact size is correct? Are letters attached or not? What form of attachment, loops or pin? Is the reverse led filled?   thanks.   

I am not entirely clear on what you are asking, but if you search “Interwar Pilots uniform” here on the forum, you will find two pretty good discussions on these. Sorry I was unable to copy the link for those for some reason. These are generally referred to as interwar uniforms once again, the change in the collar coming in the 1920’s. Throughout WWI, all US army (including Air Service) uniforms had the standing collar. The open lapels came in the 1920’s and remained in place through today really. The fabric of these interwar uniforms is distinct, and I have found the gabardine or twill used to be a bit different from the WWII examples. The color is also distinctly different. I found a hat from this era at a garage sale a few years ago and spotted it immediately from across the room because of the color and material. If you have a copy of Maguires book “More Silver Wings Pinks and Greens”, there is a great discussion on these. Anyway, try the search on the forum for more information as well and good luck.       

Recently acquired a Camillus M3.  The M3 knife in the middle of the photo is the Camillus. I feel this M3 might have been turned back in to the U.S. Arsenal after WW2. Then it was rejuvinated, rust removal and cleaned up with a fresh coat of flat black paint. Then, it was re-issued or sold years later as surplus. The two M3's on the left are guard marked. What do you think? 

Sweetheart piece.
