Thanks every one for your replies and Insights. One of the other things I forgot to mention Is that the stock has an unusually large drop which you can see In the last photo. The stock drops 3.5", a full Inch more than my Alex Henry hammer gun and has a much more pronounced decline in the comb. I have noticed this on a few other Tolley's especially those with the horn pistol grip cap and was wondering If there may have been a reason behind it?

Regards,
Rhys
