That same Rigby Mauser in .22 Hipower was sold again a couple of years ago at auction. Some ridicuous price. I preserved a photo of it from teh auction but cant find it now, beautiful little Mauser rifle with a cocking peice peep sight in its case. Looked new.

The Mannlicher Schoenauer carbine is still in existence - Last I saw it was owned by an American collector. It was featured in an American Rifleman article in the late 1980's.
That would be something to have - used on many elephant by Bell, and started its career in the Lado Enclave...

No record I have come across for the Gibbs Mannlicher.
