Could it have been marked by chicken wire, because the shape is too uniform, and netting is unlikely to have left a mark unless it was added before the paint dried. 

I'm thinking that it's not an M2 that's been repaired. But I do think the bales were replaced long ago. They just look odd to me where the attach to the rim.

Looks like there used to be a net over the helmet

Nice set.   Not sure if it was an M2 at some point though - maybe others can chime in.   Pat

Shell is WWII production front seam that was repainted for Korean War.   Liner is post-WWII production likely between 1951 to 1953.   Nice Korean War era set.   Pat

Indiana University. The Bison is their sports mascot.

Hello everyone, was recently searching through the random patch bin at a local surplus store and found the following. Looks to be either a bull/bison facing right with either the latin letters "I" and "U" superimposed or the greek letter "Ψ" Psi. Any help would be appreciated!  

Say thanks for your input. My original dia. measurement was with giant calibers at 8.5", measured with fabric tape it is 9.5" same as ebay canteen. My canteen body does not have concave depression on one side or any evidence of one. Leading me to figure this is a M-1878 oversized or desert canteen. But through your ebay tip I can conclude that the US army did have an oversize round canteen and what the neck should look like. Maybe written info about this canteen will come to light someday. Good luck with your collecting!
