I wouldn't hold to rigidly to the same production for each year and T&S may have rolled out 800 and they may have rolled out 1200 so who knows exactly for now. Also I'm sure it took longer to complete some vs. others. With additional ground truth like DRGMS and some sales receipts some estimate just might be made. Sure, I'd say 1915 with an error or +/- 3 or 4 years. If the cartridge was in use from 1905 - 1910, then your drilling may date between 1910 & 1915.
Ford, I thought you had those dims written on the back of your hand. Use your handy mic for the conversion. Range of use is given as about 1905 - about 1910.
