A quick internet check makes me believe that rings for the #1 and the tang-safety 77 are the same. If that is correct I have a set of original gloss rings from a long-gone 77 that might work for you. As far as I can tell with another internet search the factory rings for that rifle were medium height. If these might be of interest let me know and I'll dig them out to check the numbers on the bottom of each ring and take a photo so you can see condition. They were on a rifle I hunted with and may have a slight mark or two, but are in very good condition.
