Assistance with dating oil cleaning bottle please

Hi I have just been given what I believe to be an oil bottle for cleaning weapons and wondered if anybody could assist with a date or what type of weapon, 303 etc or is it generic?
On the images the stamp of 10 is on the screw cap and all the other info is on the bottom of the bottle.

 

Hmmmm. You're a gunner. Suggest a few pints of white lightening followed by a kebab. Don't expect much in the way of conversation though.

 

according to a large selling site

A lot different from a .303 to a 105MM cleaning kit and the oil kits we used for personal SLR’s in the 80s were plastic.

 

CL1 and AB64 thank you for the information appreciated.
