Again, thanks for the replies and input.
I do like the Fox and the excellent wood work. I had considered using a Sterlingworth as a platform for this gun but had moved away from that idea for two reasons, a concern over longevity with an older gun (obviously not the case with the gun shown) and my preference for a single trigger. Which generally brought me back to the BSS and a similar redo to the Fox or the other BSS mentioned. What I am weighing is the cost of doing this work, which should be in the price range I am looking for, vs. the “out of the box” RBL. As I noted earlier, I would like to be able to get out “cost neutral” or if I put in $3-4000 to be able to at least recoup the money. Although I can build a lovely shooter, which may be what I end up doing, I do not have something that I can turn over for what I have invested. So far, I have been fortunate to have guns (new and “used”) that I can do that with. Regarding shooting an “as is” field SxS, I can do that and have - but find that I do not generally shoot them as well as a dedicated target gun. While I would not want to carry a 8 lb gun around in the field, my Arrizabalaga (6-¼ lbs) or my Parker are much more difficult to control at target games. I can shoot mid 20s with them at skeet but it is work and the recoil is noticeable.
So, my leaning is still toward the RBL or the BSS upgrade (knowing I will likely not get a return for this work).
Thanks
