"Instead of the usual (IMO) nasty Beesley fore end release I'd much prefere a Rigby type lever. (they can't go wrong"

Kamilaroi, Where in the world are you getting the idea that these are Beesley forend releases? Two major releases are usually used on modern doubles, the Anson release, and the Deeley release. The Anson is usually used on sxs, while the Deeley usually used on over/unders, but especially used by German makers today. One was originally designed by Anson, and the other by Deeley, who worked for Westley Richards at the time. The Anson is extremely durable; hardly ever wears to point it won't work correctly, and is the simplest to make and fit to a double, compared to the Deeley release. What you are calling a Rigby release is also very simple in design, and very effective in use, but it wasn't designed originally by Rigby either! If I recall correctly, it was designed by W.C. Scott.
