2 Vintage Clarostat Potentiometers.  I'm guessing these are from the 1950's or 1960's but am not sure (please see photos for all the visible markings).  These read 542K and 502K on my ohmmeter (Please note that your ohmmeter might read slightly different from mine).  All posts turned smoothly.  One pot is missing the mounting nut.  These have been in storage for a long time so might benefit from a shot of contact cleaner before use.  In vintage used condition.

Photos are a major part of the description.  Please view the photos carefully for cosmetic condition as well as anything else I may not have described here.  Please ask any questions you need to.

All international shipping goes through Ebay's Global Shipping Program.

This item is also for sale on another site. I reserve the right to end this listing at any time. Although very unlikely, it is possible that this item could sell on both sites before the second listing can be taken down. In that case, the earliest sale will prevail and the later sale will be cancelled.
