Yes, raising funds is a good reason for selling, of course. I did it myself when I was about 19 - sold off most of my 'first' collection. But I do have regrets. Among guns that went to auction were a pristine - and I mean pristine - Airsporter Mk1. I couldn't bear to sell the Webley Mk2 Service though - I still have it now, 35 years odd later.
