Kevin,

There is a chance that G. Wilcke was a distributor such as Eblin, also of Stuttgart. I believe I ran into another Wilcke several years back but I didn't buy it for one reason or another. Again, the GGCA may be able to help you more. Dietrich has said one of the members is pretty good with information on dealers of the day but he hasn't volunteered the gentleman's identity as yet. Send you inquiries to: jaeger@valley.net.
