I'll look it up when I get home. The Cadet was the BSA Model 4A in .310. I think they came out about 1903 or so--like I said I'll look it up.

The 297/230 probably is a Francotte or possibly a Westley Richards. They are not a Cadet. Yes they were rifles' for Cadets, but it is not a Cadet The BSA Model 4A is the Cadet.

The 297/30 Morris guns are pre 1898. There is a bit of vagueness around the 297/230 -297/250. The literatures is contradictory about the cartridges.

I'll look tomorrow.
