If you apply for a Cat A, for a Cat B - it would be rejected,
If its processed before the State changes the law (firearms Act) which would obviously take some time....you will have the Adler in your hands...
How the many thousands of 'A' registered lever shotguns (not just Adlers!) will be dealt with... is anyones guess, 'grace period' within which to re-apply as a Cat B, letter seeking your 'genuine need'
I wonder to what length they'll 'track down' all the murder weapon gun modified extended magazine bullet ammunitions Cat D Adlers... (Sham Lee inspiration there)
