Hi Brian,
You may want to speak to Normand Fullum in the U.S.A
He makes telescopes to peoples specifications, and is a master craftsman with woodwork and such..
His website is
http://www.normandfullumtelescope.com/ and his email address is normand fullum <
telescopesnormandfullum@videotron.c a> .
I'm pretty sure he can help, so give him a try.
Theo.
