I wasn't quite sure why this was labelled as a MK3 when I couldn't see any MK3 parts but I did wonder if there were some MK3 aspects that I'd missed. Does anyone know if the cocking handle moves on these E.U. spec deacs and can the butt slide be withdrawn from the receiver or is it all welded up together solid, please? I've not examined an E.U. spec deac in the M.G. class.
