I wrote a letter similar to the Purdey letter above to Richard Gallyon, who, per the WC Scott website, now retains the records of WC Scott serial numbered guns pre 2004. He sent the following reply:

"Thank you for your e.mail. Unfortunately I have no further information on the subject so am unable to help. Good luck with your research.
Yours sincerely,
Richard Gallyon"

So, for Scott Patent use numbers, it looks like a chart will have be recreated on our own, similar to the ones above. Shouldn't be that hard to get fairly close.

Baluch are not Brahui, Brahui are Baluch
