Picked up a couple of larger size M&W 200 series external micrometers off marketplace today.
Advertised as feeling scratchy and needing a clean/service - but with low price to match I took a punt and bought them.

I’ve been unable to find a parts breakdown or overhaul document online and hesitant to make assumptions and bugger them.

This is as far as I have got with disassembling:



The blue cap on the end is just a cosmetic cover, but I definitely need to get inside the ratchet part under the larger blue sleeve as that feels nasty.

Anyone pulled one apart or familiar with the general construction of MW mics?
