Cancel for July 10: Elgin National Watch

This post belongs in the category of documentary printed cancels.  Here is an example of a cancel from the Elgin National Watch Company in a serifed type:

E. N. W. Co.

ELGIN, ILL.

___

July 10th,  1900

ENW printed cancels are more commonly seen sans-serif, and usually dated earlier in the tax period in 1898.  Are there other examples out there of this serifed font?  Please write to 1898revenuens@gmail.com if you have one, especially of a different date than on the stamp above.

It has been noted in earlier posts that Elgin cancels appear to have been applied after the stamps were applied to their documents.  Yet it is clear that these cancels were not handstamps and were applied by a device.  What sort of device was used to produce this cancel?
