I received some stray parts quite a while ago, reputedly ex-dealers stock.
Included was this conrod coated in grease/greasepaper in a little box - labelled as AMC,
8" c-to-c, so I had no idea what that might make it, since that length doesn't ring any AMC bells.
The label numbers seemed meaningless too. ?
So, I cleaned it off - and that E number looks Norton-ish.
16H Norton, in fact.
If only the t'other side was as clean, its got some rust pitmarks that make this scrap - too deep to grind/polish out. Sigh...
