I don;t mind taking it apart and investigating but before I do I just wanted to check if this is one of those common problems with a standard solution, just so I don't pull it to bits more than I need to investigating as I've taken apart an SP, ME Super and LX but not an MX yet.

The shutter release is jammed solid in the depressed position & the advance lever is also rock solid once you put it out it's 20 degrees.

Mirror is in normal position and the aperture lever is down and feels springy and normal.

Any pointers where to start ? I can't see anything obvious under the base plate but don;t want to start pulling the fron off unless I need to.

Most probably base plate unlikely to be under top plate by another one watch how it fires...

Yes good idea, I will compare with a working one.

There is a lever under there that looks suspicious but it's a case of what it's "supposed" to do.

How much did they want for it ?

125£ with a 40mm /2 I think I inspected it to see if I would be happy lens and body too small only interested in 40mm.
This is their site but well difficult to navigate & I have no vesting interest.
