Never before seen - bolt action single shot BSA 310 Cadet - what is it?

Hello All,

I have a couple dozen BSA cadet rifles, but this one is a first. Can't find any info about it. I'm posting on several forums hoping that someone might help to find some info on what this rifle is.

Although similar, its not a 1906 model because those are all in 22 caliber. Also, this one has a sliding safety on the bolt handle and a somewhat similar but different rear sight.

No proof marks - no caliber mark - only a X01 stamped at the back rear of the left side of the receiver and on the stock. There is a P. Patent also on the left side of the receiver and a patent number on the rear sight. It has the Standard BSA address with a 1907 date, and the BSA logo on the barrel and remnants of the trade mark stamp on the stock. Neat folding front site protector / hood.

any one have any idea?
