<html> <head> <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> </head> <body bgcolor="#FFFFFF" text="#000000"> Hmmm, so there isn't an official name for these little "chips"?  When they are continuous (in sections), maybe we could call them "rear bearing strips" or "rear bearing plates".  When discrete like these, "rear bearing chips" or "rear bearing plinths"?  Foolishly  I didn't make a serious diagnosis of whether the lengths beyond sounded a partial of the speaking length. And I agree that in the pic where I had dusted them more carefully, they do have a reddish tinge. Has enyone else encountered them made of wood like this? Best regards, David. </body> </html>
