Interesting Two Piece Fuze Found on M21 Practice Grenade... What Do I Have?

[J.Q.M.D.]

Greetings all,

 

I picked up this M21 today at a yard sale for $5.  I got it home and decided to take the fuze off to make sure it wasn't live, and only the top half unscrewed from the body.  The rest of the fuze, which would contain the blasting cap, stayed in the body.  The spoon is for an M205A1 and is dated 1-54.  Is anyone familiar with this type of fuze?  Looking at my collection of fuzes, I do not see any others like it.  All are cast as one piece.  Any info would be appreciated.  Thanks!

Normal M205 fuze. Good score for $5! That is easily $75+ nade.

Looks like the spoon and head just separated over the years of someone managed to unscrew it because the base was stuck?
