Here we have a metric internal bore micrometer set 903M by Moore and Wright in good used condition.

The range is 50-310mm and the set has 12 extensions, the micrometer itself, the tee handle, the spacer and a spanner all in a sturdy box.

It seems that if you want to buy a new one of these you will be lucky to get away with paying £250 so this is a bargain.

Postage is for UK mainland only.
