Copper colored rod bearings

[1952henry]

I am tearing down a running 8RT that came out of a 1952 F3. Have been extremely happy so far. No broken head bolts, no oversize markings on pistons. BEST OF ALL,no visual cracks on deck surface. Working odometer showed 25,xxx miles. Very little ridge, in fact with a little help from brass drift pistons popped out with no broken rings. Have removed 3 rod caps, all bearings uniformally copper colored, even the tangs. Journals look good. Is this normal? Think I read some bearings were this way. I believe engine is untouched, all rods in correct holes, solid skirt pistons, 1BA in valve chamber and on crank. It has the 8BA squirter rods. It has an aluminum cam gear, factory?

I hadn't started the engine in 5 years. Pulled it and put it in my 1952 Marmon Herrington F3 so I could drive it before dissembly. Compression check cold, with plugs in was from 74-85 lbs. A bit low, but considering how I tested it...
