I bought this from an AoS member a few months back.
He estimated 60-70 hours on it. I put at least 20 hours on it so now around the 100 mark.
The below is taken from the original members advert.
(This is a rare and high spec 103 variant from 1991 that sports a ceramic bodyshell and (C1) premium copper internal wiring.
It has similar spec to the 103R with 13ohm impedence and 0.25 output.
The ceramic body takes the weight up to 9.7g)

I think I recal paying approx £230 delivered so I'll ask £200 + delivery at cost.





Any questions please ask.
Cheers!!
