It was an 'In the bin" barrel, as it was in a bin with some others. Marked 10mm Auto, but nothing else. The inside of the frame needed 5 minutes of stoning, and we ordered the correct barrel bushing, and that was about it.
The slide I believe was a Fusion, and the frame was one we had in the bin. It was actually marked "Gibbs Rifle Co". and I was told gibbs sold a few 1911's with their name on them at one time. The rest of the parts were milsurps and takeoffs from various Springfields, RIA's, etc.
