Bore condition is everything.
Listed as "very good condition" so if the seller is honest, no worries there.
Interesting that the listing says "made by Daniel Fraser" and "re-barreled by Rigby". Could simply be all Rigby with acknowledgement of Fraser's patent, for the trigger?

Probably a fair price in today's market (including covid tax!)

Take-downs are a bit special...!

Brass is made from .303 British if you can't find originals.
The clips are a bit hard to track down these days but they do turn up from time to time.

Nice looking rifle BTW.
Doesn't seem to have suffered from the usual post-Raj "India" symptoms, ie rust, borers, general neglect...
