He had a number of firearms sold as part of his estate, or one kept by a relative.

They included from memory:

a .333 Jeffery double rifle.

a .450 / shotgun barrel Holland & Holland "Cape gun" made from a double rifle, where one barrel was bored out to a shotgun barrel. (edited) A 20 gauge barrel per my records.

a .450 Rigby double rifle.

I think there was a .450/400 as well, but am not sure. (Edited) Yes he did have a Jeffery double rifle in this chambering as well.

Bolt actions in 8x60S mm and 9.3x62 mm.

It would be great if these could all be identified so their provenance could be kept for the future. I know or knew where two of them are or were, and probably the family one as well.
