Hello,

As I mentioned, the serial # is 438XX and the proofs are pre 1904.
So it looks like it predates the above examples by a few years.
When was the 450EX 70 Grain cordite load officially registered.
It was a Rigby load was it not, and they did not trade mark or patent it ?
I need to get my reference books out and check it out, gun room is in a shambles though.
More books than bookshelves, and spare parts laying all over.
I need a maid service for the gun room, anybody looking for a job ?
