i own an I. Hollis & Sons gun #364xx that is mechanically identical. this is the second gun by hollis that has sold on gb recently. for myself, condition of this gun was simply to far gone to consider.
https://www.gunbroker.com/item/863868968i bid on the previous gun,
https://www.gunbroker.com/item/858847620it was cut at both ends, but seemed to me to have a lot more to work with. also, carried early nitro proofs from 80's- early 90's.
they are both WR guns finished by hollis and carry similar markings to my gun.
don't recall which of the regulars here posted a comment recently to the effect of his hollis gun being a "westley richards gold name"....without the gold and with another name.
