Ok guys sorry I took so long to get the correct info. I should have waited until I knew for sure anyway.
OK so here goes. What he has is a 1952 Colt m1911a1 slide assembly. It is in the original USGI box wrapped in a Wax like paper not cosmoline.
The slide assembly is parkerized, has "of course" military style sights, extractor, firing pin, etc. No barrel, bushings, etc.
The box is marked:
1-slide assembly
pistol, auto, cal. 45, m1911a1
s.n.l. no.b-6

Ordanance dwg. no. c-550----

So with more info any idea of the value?
