Well if you have done the yards then pick out a rifle post the pics here so those with the experience can give you as honest appraisal with out being able to actually handle the weapon. Did you sell those guns to Gun Broker or place them on there yourself P246 'cause GB would have whacked a bit on them if they resold them.
Its the old adage bloke its what your prepared to pay for a particular type of a No.4 a UF serial will command a small premium price than some No.4's as will any one still in the mummy wrap un-issued (No FTR) or a No.4 T (As you never specified a No.4 T was off the radar). A rifle can be all matching well and good, but the draws could be stuffed, barrel knackered due to poor storage or cleaning (not), stock knocked to the four winds scuffed belted & bruised makes it very hard for the guys here to assist you or to get anywhere without the item & detailed pics of it and its previous history of it the No.4 you may wish to acquire
My 3 No.4's are on the bottom of the picture 2 x 1942 Savage's and a 1944 BSA No.4
