Not sure if this is a little OT,but it is a rifled single shot and of large bore.

I would like to put a full length brass tube sight on an original 1868 Remington rolling block.
I gather these were used back in the day and would like to have one constructed to conform as close as possible to an original.
I have never seen one in person and can find nothing on the net as to how they were constructed.
I imagine there is simply a screw in aperture at the breech and perhaps a blade at the front,although I have been told some had an etched glass element at the muzzle.
The more complicated part I suspect would be the bases ,as they would have to incorporate windage and elevation.

If anyone has an original or knows how they were constructed I would appreciate it.

Cheers,

These were / are actual rifle scopes. They have a set of lenses in the tube. I doubt very much you could make one yourself, unless have some experience constructing multi-element lenses. You will need an optical bench to space the lens groups properly.

You can purchase reproductions rather easily. Pedersoli makes several. http://www.davide-pedersoli.com/accessoriDettaglio.aspx?CategoriaId=1317&lang=en

Dixie Gun works may have some. http://www.dixiegun.com/

These type of sights were used during the American Civil War (1861-1865). They mostly were used by Union snipers. This was because of the expense involved at the time for such a sight.

I have mounted several of the Dixie 3/4" tubes for some folks here. The scopes appear to be well made, clear looking, with a real fine crosshair, and look neat when on a period type gun.

The mounts are sort of funky, but servicable. Requires drilling and tapping 2, 6/48 holes for each base; no big deal. But adjusting the scope is tricky, due to the way the mounts are setup. All in all, not a bad deal though.

Good luck whatever you decide upon. Should look neat on a Roller! You might try asking over at the Single Shot Forum too. Lot's of knowledgable gentleman there.

I had a line on a fellow who had first hand knowledge of tube sights. They were NOT scopes. The scopes were similar in appearance. I didn't make it to the fellow's house in time and he is gone now. I think it was a specialty sight seldom seen. I have been looking at the 3/4 inch tube scopes on Pedersoli and Dixie Gun Works' web site. Cool! CCCB

Thanks guys,
It was the non scope version I was seeking info on,in particular the mounting system.

Perhaps you could use some mounts for the older target scopes with external adjustments. Then set up a tube in those mounts. Set up a front post, maybe utilizing a dental burr painted black. You can vary the post size by coats of paint. Make a removeable hood with an aperture at the top you can slide a cover on or off to adjust light to the post. Just some ideas. Good luck. CCCB

"NOT scopes"? Does that mean they were brass tubes without any lenses? Some were, others were true telescopic sights.
