AT LEFT - Twoidentical dials circa 1937 as were available to home constructors for homebrew projects. The bezel is about 2 1/2" wide.... I don't need an exact match to this bezel design... only a similar style and size.... Oval, round, square.... whatever....

AT LEFT - For possibletrade - S.I.F. brand lamps made in France sometime around 1920/22. No gettering.... All have bright emitter filaments that light OK on 4 Volts but I have not tested them for emission.
Would like to know the vintage and a reason for why this W. E. Mfg. Co. - Chicago sounder is nickel plated.
