Here we have a very nice example of an Ithaca 1911A1 Pistol Slide from WWII. 
Original Parkerizing, never refinished, this example shows very little use judging by the inside, where little Parkerizing has been worn away. Slight finish loss on left side in a couple of spots, otherwise nice, rich, dark Parkerizing overall.

Crisp, deep nomenclature.
Sharp, well defined edges and serrations.
Zero pitting.
Ding free other than what appears to be 4 small Armorers pin punch marks, 3 under the recoil spring housing and 1 on the Firing Pin housing underneath. No idea why. 
Missing it's rear sight and internals but we can supply and install genuine USGI parts at extra cost. 
Very distinctive "2 Tone" heattreating visible.
Overall in very nice condition, would be difficult to find a nicer one. 
Free Shipping within North America, Overseas at extra cost.
Satisfaction guaranteed.  Please see our excellent feedback from previous buyers of our Parts.
