My 2p worth...& ramblings.
Well, I've got 2 A/sporters, an early '60's Mk2 with pop up port & flip up rear sight, & one of the much maligned newer models(1969 mk4?). Both are great lookers & handle well, but I find the later one much nicer to shoot & more accurate. I also have an early '60's Webley Mk3, which is lovely to use. But my early '70's example is more accurate.
But with guns of this age, I guess a lot is down to wear & tear. And the care - or lack of - from previous owners.
On that...
I've had many Webley pistols over the years, from pre WW2 Juniors/Mk1's to the last of the Hurricane/Tempest line, via Senior/Premier, & the best of all was an early Hurricane in .22 which I've had for 20 odd years.
