I had this up a couple of days ago but didn't get a decent response, so I changed the title and will try it a gain...

A friend gave me an ingot that I thought I might use for casting, but I don't know what it is.
Here's the description:

It is a five segmented ingot that weighs 4.5 pounds. Each segment has a letter that spells out ( IMACO ) hand stamped on the back is ( GRD - 2S - 638 - R )

Hope some of the gurus here can de-cipher what all that means and give me some good useable info.

Thanks,
Wayne

Total weight 25 pounds? If so, it is standard plumbers lead

Total weight is 4.5 LB... Can't scratch it with my thumb nail. I'm hoping it is a high tin alloy I can use to make boolits!
