If a guy tells me he doesn’t want to work on a ‘Smith, and he is the top Darne mechanic in the new world, you can bet he will get some work from me.
A guy telling you he honestly wants someone else to work on your Purdey, or, ‘Smith, or, Darne, while you know he has great talent on a different make of double, is probably just being honest, and doing you a favor.

Best,
