I make the rounds at all the Alden shops every so often just for S+G's asking for shell belts....often I hear a sigh at the end of the phone. Honestly, I don't think anyone has a clue.
The best bet for a shell (non-Alden) belt right now is Epaulet. I bought a saddle shell belt from them last month and love it. Not cheap though. If enough of us got together and asked Adele and Mike to have Carmina make a bunch of belts for SF members maybe they'll be interested?
My 10 y.o #8 Alden belt is well loved and still looking great.
What about the Carminas make them worth 33% ($100) more than the Rancourts?
One (1) inch belt would be pretty narrow. Normal dress belts are around 30mm, approx. 1-1/5 in (one and one fifth inch). From what I know, the BB ones are 30mm with gold tone buckles, unless they changed recently. Alden offers 30mm and 35mm, with either gold tone or nickel plated buckles.
