I am fairly sure it is a Shikari barrel because it has the thimble for the cleaning rod, which it also has with it. The barrel is 28" long, so did H&R ever offer a 28" 45-70 access. barrel with a thimble? The underlug is also silver soldered as is the fore stock lug so the method of construction is consistent with a 1974 H&R firearm.
The receiver is a 1974 (no t-bar
) so that puts it in the window of Shikari production. It has a shikari stock set including the barrel band and the forestock is setup for a cleaning rod, not a ramrod. It looks almost identical to the 44mag shikari I have, just for some reason the barrel was not stamped. Probably an end of shift barrel/gun.
I had to shim this barrel because it was slightly loose with the forestock removed. This is not an uncommon problem with either old or new H&Rs.
If this gun had a ramrod instead of a cleaning rod then I might have suspected someone reaming out a 45cal MZ barrel. But it they did they are real pros because the ejector system installation is perfect. Having converted 50 cal Huntsmans to 50-70 govts I know modifying an MZ underlug for a factory ejector system ain't easy.
I will try and get pics up if I can talk my teenager into taking them. Me and cameras don't get along.
