Vintage E.R. Pfrerschner West german Violin

I have a West German made E.R Pferschner full size violin. It has an ebony fingerboard, tuning pegs and mountings. I am unsure about the wood the body is made out of. 

It is in Perfect playable condition. only minor scratches on front. Very beautiful sound. Model # R301E4 Serial # 432245 I am looking to sell it and i would like to know what it is worth. If you can provide me with any information it would be very nice.
