Those are cool bridges. I have a 4-string example. But can't help you with the 5-string type. Sorry. Hope you can find one.
I once had the pleasure of speaking with Jim Farquahar. He seemed like a fine gentleman. I got his phone number from a mutual friend and fellow B&D banjo enthusiast. I ordered a bridge for a very cool B&D Silver Bell #2 that I had at the time.
I found his phone number and thought about giving him a call — but I’m not sure he’s making them anymore. He’s getting on in years.
I have a tenor bridge that I really like so I recently tried a 5-string. The last one Bernunzio had with taqua nut inserts. I really like what it does to the tone on a Tubaphone I have but it’s a little too short.
