Unkown micrometer manufacturer

[TomkParticipant @tomk39956]

I have just bought a 0-0.5″ micrometer made by Osko. It came from Germany, I cannot find information on the internet about this make, There is only a crown on the frame no names to identify the micrometer. The box says it is a Osko micrometer but the micrometer is not an exact fit the box. Anyone seen this make of Micrometer.

I would say that is probably an American made micrometer or destined for USA. Graduated in 1/8th’s & 64th’s does not point to German origin. Could be Polish. Crown on body does not match up to logo on box. Cannot see OSKO on the mic’ body.

The Crown looks like the Swedish Crown, as used on Swedish Timber, and other Swedish goods, might be a clue?

Might it be a Brown & Sharpe made for export; the screw holding the fixed anvil does feature in several of theirs.

Unfortunately, one of the better resources for this sort of thing is now offline,

There are 18 captures of it via Archive.org
e.g.

Their box linings are a different colour though.
