No argument there Larry. F/M is certainly a very common combination among American makers of doubles. I cannot really confirm but on another thread it was stated that L C Smiths were bored F/F unless otherwise ordered. Lefever Arms co catalogs state the same. I have owned Baker Batavias which were bored F/F & seriously doubt they were Special Order. The F/F or F/M combination likely account for well over 75% of all older American doubles.
Likewise I also believe one will see many German guns bored 1/1 (F) in one bbl with the other bored 1/2 (M). I do not see that for a given choke theirs are particularlly tighter than ours from the card & felt days.
On the few German guns I have owned the full chokes were no tighter than my US ones. The German guns were all pre WWI guns so I presume fall within the category being spoken about. Of these the only one I have had bored full in both bbls, was built for the American market, (VL&D).
