Who do you rate as the Top 4 if Rigby isn't one of them ????
Boss, Purdey, Holland .......?

Ripp

Figures you mention are fine - could be lower, good be higher
depending on the Grade of the gun / condition etc etc.

Rigby had different grades.

Also, if it's a Webley (action) - which IMHO it is likely
to be, even better.

Ejector ?
