I stand corrected on the Grade 2 versus sidelocks. I think back then Browning had Grade 2s in most models available that were dressed up versions of the Grade 1s.
I did not mean to imply that Mr. Isaacson was not a great gunsmith, just that I am not familiar with him. In fact I am not familiar with many at all, because while I love SxSs, I have had almost nothing besides barrel work done ever, and most of my gunsmithing time has been with repeaters. I don't know that I would subtrtact $500 value for Briley chokes.
The fact that they made any selective trigger models with silver triggers is big news to me. Never saw or heard that before, ever.
I think I will stick by what I said on Sporters with 30" barrels, although I am going strictly on memory. I was selling guns back then, and I called Browning quite a few times trying to find one of those, and trying to talk them in to making a scaled 28 gauge. They told me they had a production schedule with the manufacturer and they couldn't break into that for a standard gun, and that 30" wasn't popular in the Sporter, and that they were thinking about a 28. I know I have seen several over the years and I don't remember any of those being referred to as having fitted barrels. As soon as they announced the end of SxS production I had to scramble to find a new but also discontinued Winchester 23 in 28 gauge - not that easy in the pre-internet days.
I don't blame you for not selling any of those, that is a fantastic looking set of guns. I really like the way you had the buttpads done too.
I do not mean to imply in any shape or form that I am an expert, as I know I am not. I'm just an old guy who likes SxSs.
