If I recall, the 70s vintage Lymans were much closer to the size of the Remington Beals than the actual 58 Remington. The grip was a little smaller and the overall size of the gun was slightly scaled down. I remember in the lage 80s the Italians started building a more authentic sized Remington. As to whether or not they are any good, they are probably just fine. I know they might be a tad softer of steel than those being made today, and I doubt they would accept any of the conversion cylinders made today. But that's just a guess.
