I found this one on a table on the lower level on Sunday at the Tulsa show. I do not think it was tghere earlier. It is sn 32568 and was shipped in November 1928. I also have 32561 and it was a November 28 shipment to W&K, so I'll bet this one was part of that same shipment. The grips are probably too late for the gun, but look as if they have been on it forever.
