That was made by MMC (Miniature Machine Company). An excellent aftermarket accessory for the 39/59.
Yes, they're making sights, but the rights to the sights were bought out by another company, so it's not the same company as the original. I would guess the quality would be equal, but I have no personal experience with the newer sights. https://www.sightsinc.com/Is MMC still in business, or is anyone still making their product line? They made some neat little sights for some guns for which there were no substitutes. I remember first reading about their products in articles fromthe late Skeeter Skelton. IIRC, he had them fit their compact little adjustable sights to a small frame semi aut pistol. They had a great reputation from what I remember.
