Product Overview

These 2 units are both used and in good condition with minor scuffs and scratches from normal use and storage. We have tested the recorder to power up and run the chart paper. Unfortunately we do not have the knowledge or means to fully test these units. However from our inspection and minor testing we are confident that both of these units are in great working condition.

We are including what we believe are 2 thermal couple wires, some electrical leads with clamps and the operating instructions for the recorder. The thermal paper is old and will need to be replaced.

We are offering free shipping to the contiguous 48 states.

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.
