Hello, This " Geo. Broadbent" looks like a Geo. Broadwood tuning pin. If so the threads fit the threads in the plate. Many of the Broadwoods used a combination of iron and wood to hold the pins. The wood pin block is under the iron frame about 3/4 in thick. If memory serves. It seem to work but never felt good, never felt "set". This pin (among many others) is part of the rare tuning system display in the PTGF.

Pacific Daylight Time, dsmithpiano at centurylink.net writes: I encountered a Geo Broadbent straight-strung grand piano with tuning pins as shown. Piano is over 100 years old. Although the pin shown is a bit chewed up from some previous tech (not this one) using vise grips, it it pretty close to the other undamaged ones still in the piano. No tuning lever tip I have seen will fit this, as the pin is rectangular in shape, .2”x.26” roughly. The pins are threaded into the block with a pretty coarse thread. Does anyone know where to find a hammer tip that would fit this type pin? The piano was moved here from South Africa, where apparently the techs had no trouble tuning it :} Also the piano is sitting at about 100c flat to A440, but I was assuming it was designed to be tuned at A415 anyway. Any thoughts on this also? Thanks Dave Smith SW FL -------------- next part -------------- An HTML attachment was scrubbed...
