I think I may have an answer. In my 1929-1950 Master Parts Catalog, there is no listing for a spring. However, in the Commercial Body parts section;
Group 16.280 WASHER, Door window Regulator Handle Escuscheon Plate
1931-1938 ALL rubber(7/8 I.D. x 1 17/64 O.D. x 13/32 thick)
These measurements would fit the escuscheon plate (bezel) on my truck nicely. I cannot find a part number for the bezel itself. It took me quite a while to find this in the catalog and it was not where the passenger car parts were listed (which by the way, had a spring). The counter men must have been quite skilled at using this resource.
For what its worth, there is no wear of the powder coat of the door panel from the bezel on my truck, after 2800 miles and 6 years since restoration.
