In 1996 I was originally given figures of 200 in .177 and 800 in .22 by a 'Mr.Reeves', during a phone call to BSA, but these figures were amended in 2008 during a phone call to Chris Dunn and taken from factory records, to 736 in .22 and 264 in .177, as quoted above in post #7.
Production started 14/06/1982, and numbers C0001 & C1000 were originally retained by BSA but have since been sold.
I had C0002 in .22, the first one retailed, followed by several other boxed examples, only one of which C0225 was .177, and all have now been sold.
I have seen and heard of some extremely ambitious pricing for pristine boxed examples offered on the second hand market, but don't know what the final figures realised have been.
