If there is an SM number on the give it to me and I'll check my master index
As you are aware, most of the gauges are bore and straighness however there are one or two that are a bit of a mystery or it just has been too long and CRS has crept in.
(CRS=cannot remember sh*t)
This is the only marking anywhere on that box.
