Joe, that sounds like a good point. I had never considered that. I use light loads anyway but good to file that away.
The Tolley I have looks like it spent about 80 years in its case, left behind when the doubles got to go have fun.
Kirby Hoyt has a Purdey hammer single barrel right now. A bit rich for me at the moment. I saw what I thought was a lovely Woodward last fall on Guns International, asking $4500, but I had just bought something else in that price range and, as annoying as this is, I can't buy them all.
Besides, as was noted above...They are hard to shoot. Kinda ugly. Not much fun. Usually in bad condition. No reason for anyone to go looking. Stick to the doubles, please.
