Topgun, thank you for your comments on the early Hollenbeck and it is so interesting that you have number 28 in a side by side,they had to be like sisters together in their manufacture, and I never thought about Frank Hollenback himself handling number 35,but he mustve. Thank you for that thought!
Reguarding the .32-40, I looked back at the old catalog for the three barrel gun company, it actually was a .32-40-165 Winchester Marlin Savage and I confused it with a .32-40 Remington, which actually does use a lower size bullet, .308. My old fifth addition Cartridges of the World show the three different .32-40, including the Ballard. Very interesting.
I would love to find an old Hollenbeck in bad shape to use for parts,as my German gunsmith says I may need it someday. Of interest is how this German gunsmith loves the Hollenbeck drilling and wants one for himself and his personal use. He says it is so simple, only about five moving parts in the action, which he will get into and clean later this week in Germany!
