Question about non TSO'd instruments

[yvesg]

Last winter I replaced my VSI in my panel by a smaller one. Needed the 3" space for a CDI. The one removed is a Bendix MFR TYPE NO. 1634-1X-A1

 

A potential buyer (who is on this forum) asked me if it is TSO'd. I checked the TSO database and here is what comes-up. The one I have in hand is not listed but very close number. Is it possible that this one is part of the equipment list of my aircraft? (1965 M20C) I looked but could not find any instruments listed in my books. I absolutely want to make sure if I sell it that the new owner will be able to legally put this in his aircraft. What are the options? Thanks Yves

The simple answer is that if that part was TSO approved, it would say so on the Manufacturer's tag: it would have the P/N , S/N and TSO number
