As far as I am aware John, If they are tapered one piece barrel ie. Mk1, then yes
, they only made the full length guns in .22, the .177's were the Club, although I don't know about the transition phase, ie. mixtures of Mk1's and Mk'2s, or other "specials" that may be out there (I have a faint recollection of an old thread about some funny combo's that were done)...or maybe I have breathed in too much lead this evening (did 200+ shots of bell practise earlier in the garage
)
Anyway, hope they are for your sake, and keep the photo's coming!
