Reb,
Thanks, well I was close anyway, I thought the production years were from early 1893 to 1903 or early 1904, but only form Hollenbeck's and Horne's patents...reasoning if Hollenbeck applied for a Syracuse Arms assigned patent in June of '93...and Horne was apparently applying on his own by 1903 ...inferring...that either the plant dismanteling was underway, or that that Horne had parted company by that point...

I wish I could focus better on the many aspects of these mystery triggers...but I'm making great strides right now on the subject discussed earlier about putting all the inventors of the region on a proximity/timeline....maybe patterns will emerge, maybe they won't...I have no idea where hunt is taking me...

I'll try to work on the trigger hunt tonight.
