Not going to build any more 1911's so my parts bin is up for sale: NM Slide and a brand new 45acp Kart NM barrel w/ bushing, no link or bbl line just a Kart sells them.  Do your homework and price what I am selling, its top shelf stuff at bargain price. 

Slide:    I have a parkerized 1911 slide assembly 45 acp , 95% overall (actually higher) and its got Bomar front and Bomar adj. rear target sights on it. Left side of slide frame has NM7791435 marked on it, Right side of frame has 7F067 marked on it. Barrel Bushing is stainless and marked 7267718 NM. Slide has firing pin, firing pin stop and extractor installed. This is a 45 acp slide, made for US Army Marksmanship Unit circa 1970 for competition pistol builds.  Uncommon to find these days: $350.  Here is one for comparison at $500 and its beat to crap, mine is 96% greater original condition. 
Barrel: Stainless Kart 45 acp National Match barrel, new in grease . No link or pin, has a stainless barrel bushing marked NM 7267718. Brownells sells new Kart barrels for $180 so I 'm thinking this Kart  1911 barrel has got to be worth $140.

Total : $490 if sold separate.  Buy all and roll out the door at $400 for all of the above.  Ph: 703 987 7520 if you have questions.
