Gale GT 2101 questions

I just picked up this Gale GT 2101 and read its bio. This is a different time arm than the listed and ideas? I want to refurbish this what’s my best option? 


That wasn’t helpful, there is nothing on those that I can find. I’m sad this site is so poor in response 

What kind of contemptuous answer is this?
I might as well have it in my collection and give you some info but for the rude reply you don't deserve any help at this point.
