opinions of stamp on a 480 distributor, thanks

One more thing to add on this particular unit and to keep an eye out for in the future searches. The area just above the machined diameter where the numbers are is also a machined diameter. On this one, it is so corroded it now appears to be a cast diameter. This means that at one time the entire distributor was this corroded, but now the stamped area is not. You may be able to see this on other machined surfaces also.
