Mckinney,

I emailed Paul Roberts (http://www.jroberts-gunmakers.co.uk/) with the serial # of my DR and he got back to me promptly with all of the info that he had on it.

I promised him a pint when I next visited London. I haven't been back since. I'm sure he forgot about my promise as it has been several years...but I haven't! He'll get it sooner or later.

Armbar.
