Bagpipe tenor drone top ring natural mount

Description

Old bagpipe tenor drone top Iv--y mount. This piece was used in a restoration of and older set of Henderson pipes and repurposed from a pipe maker in construction of a new tenor top.  The piece was since replaced with a vintage matching part.  Maker is unknown so see picture for details.  I am unsure of its value but I know I paid a premium fee at the time so feel free to make an offer.  Any questions please ask, I will do my best to answer all questions.
Thank you!
