Bearing brass

[lynnl]

That looks very much like what I bought as Ampco 18 bronze (from an ebay source).
Mine almost looks like it's laminated of numerous layers. Tho the layers are not all symetrically arranged.

I sort of wondered about this thread, trying to tell what it is from the look, that 'look' afaik is the look of continuous cast bronze, could be any alloy. Now as bearing bronze is common, and that is how it usually looks, you may may make a reasonable guess by the appearance but if its critical, id' say all you really know is that its continuous cast bronze.
