This came through the workshop recently and we wanted to share a few photos as it’s such a lovely example, and we don’t see many of this mark! The MK4 differs from other models by having a different loading tap (similar to the early models but without the self opening feature, but a completely different design to the later marks).

This one was in for loading tap issues, and when tested was down on power and showing the standard signs of buffer washer break up and piston seizure. Received the full power plant upgrade and now shoots as well as it looks suggest it should.
