Got this in a recent astro buy, an unusual vintage refractor finderscope bracket with a small unbranded 30mm finderscope in it, possibly not orginal.
What's interesting is the extension cast into it that looks to be a camera platform. Also the diameter of the tube the base bolts to was quite small, around 2". Seems like a pretty fancy bracket for such a small tube and thus objective, perhaps a 40mm?
Another interesting aspect of the bracket is the 1/2" hole with thumbscrew that is likely to clamp an arm or some such, possibly a sun projection plate arrangement?
Anyone know anything about this bracket?
Thanks in advance for your input.
