Hi David,   unfortunately the number painted on the hood is the vehicle's military registration number, and is completely unrelated to the unit it was assigned to. Can you post the pic?

What a beautiful 11th Corps badge and a tough one to find! I have one super clear ambrotype of an unidentified 11th Corps soldier with a similar silver badge pinned to his forage cap.  Paul

24th Constabulary Sqdn, then became 524th

Two F-14, VF-154, Fighter Spy buckles that recently sold.    

Found this one on this forum.  WorldWarPatches owns the patch https://www.usmilitariaforum.com/forums/index.php?/topic/56185-tank-destroyer-ssi-and-insignia/page/25/#findComment-3011762  

I appreciate the comments friends. Love the collection and love the pic of your Dad on the farm.   I have 5 of these now due to the disease I have. 1 of anything collectible seems never to be enough. Well within reason anyway. lol I am more intrigued by these cover alls, for some reason, than I am by the frog skin uniform shirt and pants. By the way, these coveralls are a lot lot cheaper than the frog skin uniforms. And they pop up on ebay often enough that you can snag a pair sometimes sort of reasonably for todays prices. I saw one thats on ebay now thats spattered with white paint from a UK seller. Only asking over $700.00 for those..... Only... lol And ruined with white paint too! I'l pass on those...... :-)  

Some Italian made

Some harder to find variations and vet altered pieces

There were multiple types of removable spikes/plumes holders.  Can You take a photo of the version you have?  I have a few.   .  

Well this why none of the rest of us have a pair… you have them all!     All levity aside, you are very lucky, awesome collection!
