19J Howard Bridge Model with '05 and '08 Pat'd Dates

[sabphd]

I recently obtained a 16s, 19J, Howard bridge model, S.N. 1,050,323 with the "straight" bridge and jewelled safety barrel. It is marked PAT'D '05-'08.

1. How does one explain the dual patent dates?
2. Has anybody ever seen a 19J bridge model marked PAT'D '10?
3. Has anybody ever seen a series 1,which is an early 19J bridge model with the straight bridge and going barrel?

Does anyone know what the 1908 patent is? I think 1905 patent is for the motor barrel. If we knew what the patent covered, you could examine the movement to discover whether it was mismarked, or whether it has both the motor barrel and the other feature.

Where does the reference to the 19J Series 1 come from? Is that from ad copy somewhere? The watches marked No. 1 are 21J and I have certainly never seen a watch marked Series 1.

I have a 1909 Howard material catalogue. It lists the different watches by model year (1905 on the 16s 3/4-plate, 1906 & 1907 on the 16s bridge model & 1908 on the 12-size). These dates are the same patent dates stamped on the movements (although I'm not sure about 1906) which had led me to believe (perhaps mistakenly?) that the patent may refer to movement design or layout.
