There is an extremely rare TV140 on the classifieds right now.  Too rich for my blood but I am sure someone here would appreciate it.

You mean the "Tele Vue 140mm f/5 Apochromatic Rich Field Refractor"?

Only 37 made! Wow.

This 4" F10 achromat is definitely a rare one!  It was the first 4" refractor I ever owned and was made by a local optical company in Lancashire, England between 1981/83. Only ten were made in total. It had a nice mahogany tripod and brass draw tube, with a powder black main tube. It was only good upto about 150X, but it gave some very nice views of star fields, comets & nebulae. It was this scope that gave me my first really memorable view of M42, so I can't criticise it too much. The mount was a pain, but as I only paid £99 for the whole thing I shouldn't grumble. I seem to remember I had a 25mm orthoscopic and a 12.5mm orthoscopic and that was it. The scope showed quite a bit of red but I didn't care as it was all i could afford at the time, and it was certainly good enough to set me on my path to refractor heaven. Plus it was cool to look at! I never yearned for a reflector!

I have TV-140 #33.  I have seen the total of 37 referenced many times but I have never seen another with a serial # larger than my #33.  I also have heard that TV has never disclosed the precise # so I wonder if there really are 37 and where that # came from.

The 12-inch Zeiss and the piggyback 9½-inch Zeiss at the Griffith Observatory are both pretty rare.
