I have a buddy with a Shiloh Sharps 40/70, with a scope he ordered with the rifle, vertical crosshair broke. He thinks it is a early MVA scope, but no markings on it period. He is contacting Shiloh to see who made it, about getting it repaired. In case this is a no go, anyone know someone who can fix and gas the scope, all help appreciated.
Ebay sells Tungsten wire for crosshair repairs.

If you’ve decided to attempt replacing the crosshairs yourself, where
do you start? What size wire is required and where can you buy it?
Since I’d rather not experiment with black widow spiders, I’ve
purchased 3ft lengths of tungsten crosshair wire from a fellow on eBay
with the “handle” of “lostabundle”. Search for “crosshair wire”. He
describes his fine wire as having a diameter of 0.0005” and medium as
0.0015” diameter. For target shooting or match competition I prefer
the 0.0005” diameter wire which I consider very fine. The 0.0015”
wire will also work. So as not to lose the crosshair in the image
background, medium or thicker crosshairs are a better solution for
hunting. Other sources of crosshair material include dental floss,
human or animal hair. Human hair ranges from 0.0015” to 0.004”
thick. Dental floss is made up of many very thin strands which are
strong and around 0.0008” to 0.0010” thick and, if installed correctly,
can result in a nice durable crosshair.
MVA should be able to help

I believe mva reticles are etched on the lens
I can only speak to doing it myself for older target scopes using the tungsten wire referenced above. Not a terribly difficult job. No clue how MVA reticles are achieved, but if they employed the same system as the Unertl, Litschert, et al did then that's the route I would take.
Were they gas-filled? I'm thinking probably not.
Call MVA, they can get you fixed right up, changing reticles in those scopes is a fairly easy thing to do, just loosen the level adjustment screws remove the rear objective tip the scope up and the reticle tube slides right out. Might also ask them for one of their scope manuals when you talk to them
If you remove the reticle cell to ship just the cell to MVA, get a short piece of 1/2" PVC plastic tube, and cut it slightly longer than the cell. 1/2" PVC is 7/8" ID, so the cell fits right in it, and protects it both ways for shipping. Cut it just long enough to install a small sheet metal screw at each end to keep the cell in place.
I can't say for the earliest of the early like a prototype???? but MVA scopes are marked and have an etched glass "cell". No wire crosshairs. A picture of the scope might be a big help in ID'ing it. It is a good chance the scope is something other than MVA.
Seeing has how the vertical hair broke I doubt it's an etched system.
MVA scopes aren't gas charged and don't use cross wires.
DZ scopes aren't gas charged but do use cross wires, and they will repair/replace those fairly inexpensively.
Could possibly be an RHO scope but not sure if they're gas charged or not.
Ok, so far he has found out that the scope was made by an individual who made them as ordered, back in the day, someone out there close to the Sharps was made, he thinks. Their record keeping is not that good, and they are looking back at who made scopes for them back in the early 2000's. Could you provide a pic of DZ or RHO scopes?Quote:

You can see the DZ scopes on their website. Like Marlinman I don't believe RHO made anything other than full length.
There should be a makers mark on the scope you have.
Odd that Shiloh's records don't show what scope the rifle was shipped with.
It is a RHO.
That might complicate things abit. Some of those had multiple crosshairs.
This is from 2010 but contact info here.

I am confident I can fix the scope after talking to him and reading others post her. It is not gas filled by the way. Thanks for all the replies guys, this site is a wealth of info and fine folks.
