Product Overview

This unit is in good cosmetic condition with some scuffs and scratches from normal use. While it does have a broken piece ( shown in photos ), the micrometer head is in excellent condition and operates smoothly with no issues.

Unfortunately we do not have the digital readout or any manuals to include in this listing. Sadly we do not know if the broken piece can be repaired but the micrometer would make an excellent replacement part.

Due to the broken piece we are selling this item as-is for parts or repair.

Item was as described, and very fast delivery!

5 stars across the board for every seller rating category, and I would buy from this seller again. And per my request, the capacitors were also very well packed for safe delivery.

Obtainium have been a very helpful seller to me.

In recent times I have had a few items go astray enroute to my address in Australia. This seller was most helpful & encouraging, regarding the onward tracking & eventual safe delivery of this item. This item's arrival in good condition was a joy to me as, it was a rare part that fitted my military comms. Well done seller. I would gladly recommend this seller to all potential buyers.
