Well I should have it in my (admittedly not very experienced) hands next week. And I will certainly report back on any findings.
I presume rectifying stuck Mk3 drums isn’t a job an unskilled armature... ?
Incesntly as the firm is still in existence I have sent them an email asking if they can shed any light on a model No32 with there logo on it. But given it was a few years ago I’m doubtful of anything coming back. However should anything come of it il feed back to here!
Thanks for all the responses!
