I will go out on a limb and Hazard a guess,
Nicely restored A (not perfect) will sell for $3k incl nice fresh running motor to get it to this point bugdet to spend between $2500 and $5000 depending on whom or what you know.
As is maybe you will get between $800 to $1200.
I have owned 5 x RMA's, gotta luv them they seem so lite, I currently own a 125S and a 125T
