<html> <body> Mark, I agree with Alan. But you have a good tech there in Madison, Bill Bremmer. I'd suggest giving him a call and asking him to look at it. I don't know if he will or not, but be prepared to pay him something to do so!

It is a Thomas model PT vertical.  Serial no. 041384.  The nameplate lists the manufacturer as Thomas Organ of Sepulveda California. Pierce atlas lists only Thomas Piano (not Thomas Organ) as being from Sepulveda.  So, how old is this, anyway? The theory of operation is standard, but the only action components that look standard are the damper felts, hammers and shanks.  It certainly isn't a high-grade piano, but is intriguing from an mechanical design standpoint. The plate is a weldment and the keybed (also a weldment) is attached to it with machine screws and locator pins.  The action is removed extremely easily by flipping two spring steel clips on the top of two action brackets.  Components are either plastic or stamped steel.  For instance, the spoons are an integral part of the wippen formed from sheet stock.  Backchecks are stampings with  buckskin glued to them. Adjustments (including key height and dip) are made with plastic jack screws.  Wippen, hammer and damper flanges are insert injected plastic pieces with (what appears to be) spring steel inside.  They fit into approx 1/2" channel rails like mini plastic clothes pins with the springs reversed.  I can't find any screws holding these in place, either. The problem is the damper flanges have a small protruding ear that retains the damper (torsion) spring end.  The spring torsion places tension on the ear and many of these ears in the bass flanges are broken off, leaving the dampers to freely wander in space somewhere between the strings and the damper stop rail. Questions:  Are these flanges of the soon-to-be-powder plastic type like old plastic flanges or elbows?  Are new flanges available and, if so, will standard center pins work?  Or, I'm wondering if I can get a dab of epoxy to serve as a prosthetic ear on the existing broken flanges to hold the spring end (I'll try gluing a broken piece but I doubt it, though).  Is it worth it to replace or repair? Disclaimer:  Please correct me if some of my observations may be off a bit:  It's bifocal time. Thanks for your comments and suggestions. Mark Ultsch, RPT Madison Chapter</blockquote></body> </html>
