List, After 20 years plus I came across a most unique concept which in the beginning, I could not figure out. First thing I noticed was an unside down 'L' shaped wire mounted on the top of each jack lever, which when at their rest position, inserted themselves into the hammer butts which conveniently had holes in them, each with a felt pad for the wire to rest on. I was totally baffled at the reason for such a wire device until I needed to remove the action to do a repair on a broken hammer butt brass rail part. It was at that time that I noticed something that was customarily normal for older uprights to have, but this one didn't. Anybody care to guess the reason for the upside down 'L' shaped wire before I reveal what else became self evident which explains the why? For anyone who might have already experienced such a thing, please refrain from giving it away. Keith McGavern Registered Piano Technician Oklahoma Chapter 731 Piano Technicians Guild USA
