<DIV>Hi Terry,</DIV>
=
<DIV> </DIV>
=
<DIV>What is this piano that you're working on? I don't see a =
metal
=
spider, so I'm thinking it might be that Knabe you =
mentioned.
=
</DIV>
=
<DIV> </DIV>
=
<DIV>BTW, I am going to go look at a Bush & Lane Pompeiian in =
Michigan
=
next weekend. It is one of what B&L called =
their "traditional
=
uprights," which have the most massive plates of all the B&L's, is =
a full
=
58", with the same speaking-length scale as my current one but longer
=
backscale in the bass and also longer backscale at the bottom of the =
long
=
bridge, and bass bridge direct to the board (not cantilevered). =
The
=
Pompeiian is also my favorite of the cabinet styles I've seen so far =
(same as
=
I sent you a picture of last year). This vintage (1919) should =
have the
=
Wessel Nickel and Gross action, and maybe I'll be lucky and it has =
lost-motion
=
compensation. However, while these models do have curved =
sounboard rims,
=
they do not have the plate-flange supported pin-block with the =
upward-extended
=
soundboard, but I'm not sure what extension in that direction =
does anyway
=
(my current one has the extension, and does have an enchanting lower =
midrange,
=
but who knows why?). Any exciting developments after next =
weekend, I'll
=
report further.</DIV>
=
<DIV> </DIV>

<DIV>Regards,</DIV>

This rib is now about 37.5 inches long. I don't believe its =

Although my
