Thanks for the responces. I do appreciate it.
I've got a regular Hand-Rifle 45-70 on order through my local dealer right now. It would be very nice to have a Trapper model with a Mannlicher stock, so this may be my next purchase.
I didn't see the Trapper barrels on the H&R1871 site. So, maybe an alternative is to either cut this new one, or have a new barrel one installed, and shorten that. So many options, so much enjoyment.
BTW My brother owns my first 45-70 Handi-Rifle, so I wanted to get a new one. I've also owned two others, both were 30-06's, but sold them off.
