ReconScout if you're having them made in the PRC I'd suggest selling them for a much more modest price more in keeping with the actual cost. Price has a lot to do with demand.
When I did the IWS brackets I had them made here in Canada, and while they did a very nice job and I'm sure for a good price by local standards, but by the time the unavoidable hand finishing, blasting, phosphating and painting was done, there wasn't much profit in the venture.
Overall though, I doubt there is that much demand for another reproduction of the same bracket. I'd suggest you come up with something a bit different: perhaps a 30mm ID on the rings? That would meet a real potential need in the market.
The real question is will they collimate to the original pads on original rifles?! Not just zero, but actually collimate.
And BTW, your ring caps look too thick in the model you posted an image of.
If you want to take a stab at the original No.32 brackets, I'd suggest you use the very early rounded or Rose Bros.(?) casting pattern, rather than the rougher, squarish N.92 pattern.
