Hi Mike,
Simspons LTD have a few Erufrts for sale...their prices are a bit high since they are a retail shop...prices between private collectors are usally 15% or more less expensive :

The chip in your left grip panels hurts price some but your missing side plate is a real problem if the original cannot be located and you replace with another one not numbered or not matching your pistols last 2-digit of the serial numbers. I also noticed your grip screws are not Erfurt proofed...
Does you magazine match the gun's serial number ? If not, that lowers price a bit too, as well.
Regards,
Pete...
