Not sure if I'm in the right part of the world here, but I thought I'd see if anyone could tell me more about this level. Google gets me nothing, so here it is:
And the inscription:
Sorry for the less than stunning pics. Friend at work gave it to me the other morning; said one of his kids gave it to him from a garage sale or something, and he was cleaning out his shop and had no use for it.
Pretty nice for the price; wooden box a little battered, but I'm not complaining.
It seems to be 0.0035 per foot sensitivity, and is shown as late as catalog #9, which I have. The catalog isn't dated, but appears to be '60s, so the level need not be old.
Provision of wood box with sliding top should move it earlier. In the catalog I have, the box is hinged top, and available only for the 18" model.
It appears in catalog No. 8, and the 1959 price list has the wood box as a $6.50 extra for the $17.75 12" level.
Interestingly, it does not appear in Catalog No. 7.
One more thing, I have a 6" #58 level and the vial is satin chrome which I think would make it a later model, so I would agree you have an earlier level. A comparable Starrett can be had for $210 (12") or $320 (18") so you have some bragging rights.
Thanks guys, that firms up what I was sort of guessing.
