Update,The pistol,with another bb pistol went for £90,I didn’t get it.Thanks for all reply’s JIM
In time you will find a rifled one or more if you are patient.They are not common,but of the seven or eight Juniors I have two early post war MK1's have rifled barrels and the only MK2 I have also has a rifled barrel.
I don't know if the wood or tin grip Junior's were ever available with rifled barrels.
Some look down on Juniors in favour of the larger Webley over lever air pistols,but for me the Junior is the nicest of them all to plink with.I love its compact handy size,low cocking effort and punchy power to weight ratio.They are also very well made and finished the 'plum' brown trigger guard and grip frame model MK1's being my favourite.

Though I have a MK2 they are of relatively poor construction by comparison,but shoot well.
