There should be a pair of Hollands over and unders in 16 bore, an old 416 Rigby and a good old english double rifle that has seen several generations of use. All should be set up for left handed use.

But just checked the cabinet and there is sadly
just my W J Jeffery 410 side by side Boxlock

There was a 410 Single Barrel "English Made" (ie no makers name) on a Ward Patent action - this is now with my nephews where it resides alongside a Stensby boxlock ejector.

I am keeping my eyes open for a nice 16 bore boxlock or even sidelock ejector for my wife to use to replace her 20 bore Rizzini.

And I want a 12 Bore Magnum side by side duck / goose gun - fed up with a Benelli

I do also have a very nice 12 bore AyA Coral over and under, that sits alongside a Ferlach built 16 bore / 7x65R combination gun and a Heym SR20 bolt action rifle in 243.
