The first slide was a good fit ,the barrel married good. Accuracy was very bad with a XXX ( I wont name the company) bushing better with a common bushing but still not good. I am putting this Rock slide on with adjustable sights. Barrel is a better than fair fit, using the XXX bushing and full length guide rod. Testing for cycling showed it was excellent. For all y’all that want that tight slide to frame fit I got to tell you with this old RR frame this one rattles like a Tin Lizzie ( a model T Ford for y’all young folks ) going down a brick street. But we will see how it turns out when I am done. 1911’s Forever

Just FYI it doesn't look like a Colt frame to me. Possibly a WW2 Remington Rand?

Agreed, it has a WWII “rushed” look to some of the none-critical machine cuts. Possibly Colt but s/n would tell.

Accuracy doesn’t suffer as you say based on the brand of the bushing, it’s more dependent upon the size and resulting fit. You need to measure the the barrel OD and slide ID very accurately and then size the bushing accordingly.

On the Caspian/ Gold Cup build that I did eons ago I used a NM bushing. Was a bear to fit but I eventually got it installed, made for a tight 1911. Good luck on your build.

For me the tell is the lack of a VP proof mark and the short "ears" at the rear of the frame.

Yep, short ears, lack of acceptance stamp. Only one inspector stamp on guard instead of typical two. Milling marks on A1 cut looks like RR.

Not sure but it looks legit, not faked, it is forged and milled, not cast. Other side pics would tell the tale. Lunchbox?

if I had a spare frame like that, I’d build a MEU(SOC) replica. In fact I think I do effectively have a spare WWII frame; I recently got a CMP gun with a high grade RR frame but badly fit Colt slide. Either sell it or build something interesting out of it; too crappy as the CMP sold it to leave as-is.

Daydreaming aside, I definitely agree that frame looks either non-Colt or otherwise interesting.

You are correct on that and I did . Here are some more reading I took that lead me to believe the slide was out of spec and causing the poor accuracy ( 10 to 12 inches low at 25 feet ) these pictures show the Rock slide and the protractor app showing right at 1/8 degree at the barrel hood this should work out to right at 1 degree at the barrel end. ( sorry no pictures of the app not enough hands to take one ). The second picture shows the other slide as you can see the bubble is back and barrel is downwards app showing a tad over 1 degree so at the other end barrel would have to much downwards angle. At 25 feet it would be a bunch.
the slide in question was a bald one the we finished the work on. Sights on both slide are very close in measurements. When I get it finished a test firing will tell the tale. Up loaded 2 pictures and got 3 strange things happening on this site.

Here is a picture of the other side. The hand put on number as I recall was from the Clark company doing some work on it as the seller told me this was a practice pistol for the other one I purchased with it. And it was reworked by the Clark company and was marked as such.
I sold the Colt slide some years ago as it had a lot of holes in the top and a long Bormar sight.
Might not get a picture last post I downloaded 2 got 3 now it won’t download any. Site must be having trouble.

Whatever it is, that is a cool old frame for a project. I’d love to find one like that; not as easy these days as it used to be!

Got it together and checked all the safety and checked for trigger follow. Cycling great , already did the trigger work 3 1/2 pound pull smooth. Pull the firing pin and did some target sighing, sights look close. Try to get to the range after the holidays. Most of my builds are from 80% frames. So this one is lots of fun even with all the problems the first slide was giving me. Think it’s my first non ramped 38 Super. All my others 38 supers are ramped.

You are correct I did some checking and it is and RR frame guess I will have to change those grips. Thanks for the heads up dsk.

Don’t know what’s going on here downloaded one picture got 3 this time. And can’t get rid of the two extra ones

Here is a picture of the competition Colt from the Clark company. The RR was his practice pistol I bought them as a pair back in the late 70’s or early 80’s if you load some good rounds that Colt will put them right where you point it . WOW took 10 try’s to get these pictures to load .

In all the years I have tweaked 1911s I found that it doesn't really matter if the slide rattles on the rails if the gun will chew the center out of a Bullseye regularly. What matters is that the barrel goes into full battery in the exact same way every time the slide cycles. Consistency is important - tightness not so much. I have shot many old Colts that rattled but would chew up an X.

If this one shoots good I will have to name it Rattlesnake and get some grips with rattlesnake emblems. 1911’s Forever

A good rib kills 1/3 of felt recoil.
