We've learned that this is an 1807 with 1907 stock... apologies for any confusion.
It has a 2 stage trigger. Not sure how many rounds, but we understand the barrel is 1981, with the stock new around 2000. It has had regular club use by the current owner for about 14 years, with annual Anschutz servicing at Bisley. The barrel has helped keep its owner in X class for the last few years and has only been replaced in favour of a Border. No known probs and a recent quick batch test showed a best 10 shot group of 12.8mm at 50m, next best was 14.6mm, so it looks like it easily holds the 10 ring and is still a good barrel.
