I collect mostly antique stuff, with the exception of Triple Locks and the occasional Registered Magnum.

I tend to prefer originality, so Ropers are generally after market.

Having said that, I certainly admire the workmanship of "Ropers" and "Roper like" stocks.

My understanding is that Ropers are, unfortunately, not marked as Ropers in any manner or form.

How does one determine true Ropers vs Roper like stocks and how is a valuation assigned?

Any good references relative to Ropers and Roper like stocks?
