Thanks very much Drew 451..possibly something i could work with/adapt, would need to fashion a whole new rail guide though. Would much prefer an Original though.I'm also after an original Dioptic for it.., just as a spare!! Spare's appear to be very difficult to come by. Any idea's ? Yes the Haenel is certainly worthy of a smoking jacket..!! purchased a Wooden Joseph Manton case, bit over the top but looks and fits nice and snug.
