Scovill Model 1907 M WWI Fuze

 This is a WWI era Scovill Model 1907M Fuze. I picked it up from a guns salesman at a convention. I paid $20 for it. It has been fired because the rings for the mechanical time adjustment have been slightly squished as if it had hit the ground but did not detonate.It appears to me made of brass and a separate type of metal on the base. The bottom has rusted a bit but the brass shines up. This is how i can read the lot number and model number. The lot number is 2289-21. Another unknown identifier is P8289-18.
