It may sound a bit harsh but there is allot more than just buying a No.32 and chucking it on so to speak Peter L has expounded this theory a thousand times it has to be fitted to the rifle perfectly, I cannot remember where or when I heard/read but fitting up they had 2 thou to play with getting everything right with the pads/bracket and having the scope centered exactly on the horiz/lateral axis of the rifle bore (probably have the terminology wrong).
Either way it is a T and was deemed to be acceptable for conversion to me it is above the normal No.4 but how much you are willing to pay is entirely up to you as your the person considering acquisition but it will need to be pristine I hope it is and you reach the right choice, if it has its transit case then thats good but you do not say the price perhaps due to swoopers.

I like to think the forumers here can and do offer honest opinions and are not swoopers, and by this definition I mean(has happened to me) you say what you are interested in a price and location and others track it down get the deal and not you SWOOPERS they exist believe me they do and I for one am not one of them. By the way Merry Xmas to you all and a Happy New Year families and all me I managed xmas off this year yippee........
