Jim - Robert and I both collect these by maker and pin fastening. We put together a "database" with makers and fastenings
Thanks to the fine article by Wilhelm and Mathieu I started to put together my little collection that now includes 46 variations by maker and fastening. I would say the toughest ones to find are by Wilhem Kolwitz, Walter Demmer, E.K. Haass (believe that's the spelling) and Gustav Brehmer.
Franke is not especially tough to find and of course Deschler is always a good one to have since they are a well known maker. I will say that the pin crimping on your Deschler is one I am not familiar with.
Having said that, not too many people are crazy enough to collect tinnies by maker etc. so the prices would likely be the same regardless of maker. I doubt the average collector of tinnies (especially such a common one) could care less about the maker as long as they get a nice example.
