Great looking guitar, Mike!
I think PFG on your build sheet is really PF6.
Your set of pickups is a different molding from earlier '75s, take a look at my guitar in the showcase section (75-137) and see the difference.  
 
Appraising your guitar is kind of subjective, and one of the main questions any Alembic owner is going to ask- 'how noisey is it? Does it need the electronics upgrade?'..... with that said, gtrguys' ballpark is right, but i wouldn't let go of mine for that considering the recent refinish and electronics upgrade!

Thanks so much guys for your valuable input. I am really not hard pressed to sell my guitar, but due to an industrial finger injury some years back, I can only comfortably play the fat strings of a bass now.
I have heirs with the intonation of a rusty hinge so it does not look like heirlooming it would produce much more than a giant canoe paddle.
I do appreciate the integrety of the Alembic community so I will probably Hang Around it for awhile. Thanks again for everything and also the tips.

Your base is gorgeous!!! I also play a short scale Fender Musicmaster (early 1970's era) It has been Tweeked Up or (Ruined) before I received it with a radically angeled Jazz Bass pickup near the also added Bad Ass Bridge.  
It plays and sounds really great so that has been my redeemer for playing over the years. I tried to add a photo but lost not only the photo but the original post as well. Maybe I'll figure out how to post a copy in the future. Thanks for sharing the pic of your bass. (I can't help but wonder if the guitars have even serial numbers and basses have odd numbers ?)

Wow. I just rechecked the scale length of my guitar, and it is indeed 24 5/8.... I never had a spec sheet, but I can swear Mica told me over the phone that it was a SSG, and with a quick check with measuring tape I assumed was Gibson's 24.75 standard....  I learn something new everyday!

I'm going to try yo insert a pic of my bass we spoke about several weeks ago.
