Had the 80 about 50yrs.Its been a fabulous tool with every conceivable mod applied.i.e.phos bronze piston wts .transfer port enlarged.top hat spring guides.
Many years ago i was at a show and was talking to T.ROBB he told me to remove all the gumins i had fitted and fit 'this spring'.Well guys 24ftlbs was the result in .22 with a bark that was a joy to hear.
I have both 177 and 22 barrels with loading levers attached so its a quick job to swop over.
Question is if i purchased a .25 barrel would this also fit and work on the old girl?.I realise this might be a little more expensive than the last 80 barrel from John Knibbs which cost the princely sum of £11 yes 11.
Grateful for any ideas with this and hope my thread was not to boring.
Cheers ;Richard
