I came home from a local gun show with this 2-trigger Frank Wesson rifle, with period scope mounts. I am thinking Mogg mounts maybe?
I suspect they may have held a tube sight, rather than a scope because the front ring will accept a 5/8-inch diameter and nothing larger. Although I understand some early scopes were that diameter.   
I would like to get a suitable tube sight or scope to install. 
The front ring has a channel cut inside for a rib on top of the tube to pass. 
Can anyone share pictures with me of proper tube sights or scopes in this type of mounting?
I know I will need to make the split block to go around the tube between the "rabbit ears".
Even better, does anyone have the items I need, and would be willing to part with them?
The rifle was tagged .32 cal centerfire.
The bore is like new, and mechanically the rifle is tight and in barely used condition, should be fun to shoot.
It's definitely centerfire and does seem to be about 32 but I am still working out what the chambering actually is.
A 32 long colt just rattles around loose in there, and a 32-20 case starts good but stops about 1/3 in, so I suspect it is tapered.
Does anyone know what round this rifle might take?
I saw some talk on the internet about a "wesson 30-30" which can be formed from a 357 max case using dies, but I know nothing definitive about it.
For sure I wont try anything in it unless I know it is a good fit and a proper load. Any specifics in that regard are welcomed.
Thanks for any info/help you guys might give me, so I can complete this old rifle and have some fun with it! 

Thanks Dellet tonight if I get time I will slug the bore and take some measurements of the chamber, see if I can't narrow it down more.
Most urgent for me is to get a 5/8" diameter scope or tube sight back on this old boy.
Sure would like to find that, I am sure one will turn up eventually.

Can you give me details/dimensions/photos of your tube clamp, so I can machine up a close copy of the original?
That would be a major help!
I can provide you details of my rabbit ears in return, if that would help you out

I have a form die for 30-30 wesson
. Need .357 max parent case. moodyholler

Without knowing if mine is for sure the same size as your base, I doubt measurements will help much. Your hole to slip over the scope will determine the center hole size, and the "ears" will determine the width of the block, plus the two vertical ears have the slots that determine the size of the through screw that clamps those ears to the block.
I'll get a picture taken of the block so you can see how it's built, and then you can make one to match. Only part missing on my block, and your base is the screw that goes through both to secure the height adjustment.

Thanks, I have 4227 here so I’ll try using that.
And yes, my plan is to make the block to fit my ears I just need to see a photo for original shape/features and finish, to copy.
My rabbit ears have the thru bolt that goes thru the block with thumb screw to tighten. Or I thought it did- is there a second one it takes that I need also? I figured this one passed thru a hole in the block below the scope tube.

That’s fine I appreciate any info no rush. We can compare my ear space to your block dimension, and if it works for you I’ll give you a detail drawing of my rabbit ear and elevation screw and knob
