There is an ad that runs monthly in Rifle magazine for custom made doubles at
affordable costs.
On our way back from Africa we had a layover in London. I grabbed a cab and went to Holland and Holand. Only gun store I've ever been in where everyone was in a coat and tie except me. Anyway, they started pulling doubles off the shelf while wearing white cotton gloves. I kept turning my nose up as I had to have a .470. Only thing to do was have one built. Money was pretty loose at the time and I probably could have bought one, but you had to make an appointment for fitting, and you had to come back for a second fitting in 4-5 months. You could expect delivery 5-6 months after that. Gorgeous guns, they had some of the prettiest walnut I've ever seen. Fit and finish were perfect.
At the time the dollar was weak and the gun would have wound up costing about $25,000, and was probably a good investment, as they are now around $100,000.
Anyway I bought 2 tattersal shirts at $100 each, and offered my thanks.
I still have the salesman's card in my Rolodex.

BTW- They threw in a set of dies made from the same reamer as the gun. Thought that was damn nice of em.
