Happens that that's what I used to do for a living. Oh damn, still do sometimes. Let's see
about 500 repairs a year by 15 hmm that's 7,500 odd repairs!
Also belong to a couple of useful groups one being the Antique Telescope Society and the other a binocular group. I have always enjoyed restoring these types of things! Most are love jobs(
) that you can spend hundreds of hours on, but how do you charge someone $6,000 for a repair?
Ohh well, back to the grind .... sorry, polish now.
