Does anyone know what year webley changed the writting on the fore end of the hurricane.

From
HURRICANE on the side and WEBLEY & SCOTT LTD BIRMINGHAM ENGLAND on the underside (slightly etched into the fore end).

To
WEBLEY HURRICANE on the side and WEBLEY & SCOTT LTD MADE IN ENGLAND and two F symbols on the underside (slightly raised on the fore end).

I have a few of theese pistols and i would like a rough idea of there age.

Many thanks
Chip
