MF135 - Can Anyone Identify Please

[1968 MF135]

Hi,
Have the 1968 MF135 stripped for some other work and am slightly puzzled with my Dashboard layout - Maybe the tractor started life as an Industrial version? (traces of yellow paint under the red)

Firstly I seem to have an extra gauge on the dash (the LH big one in the photo below) this is connected via a drive cable to the transmission, but I cant see any photos of a dash layout like this anywhere:

Secondly, can anyone identify what this is with two wires going into it? this is under the battery carrier on top of the transmission:

Thank you for any info

I do believe it's the safety switch that prevents starting when the hi lo is not in neutral, the gauge is probably a speedometer.

Is there no symbol on the instrument?

You probably have a MF2135, the industrial twin of the 135.

You're gonna have to change your handle now.

Hello, can anyone identify and tell what exactly this bolt is called or where to buy one . It is on the fuel filter of a massey 135

It's not really a bolt, but a bolt could be used. It's a plug, Massey number could be 731364M1 with a 731364M1 washer. .It is a 1/2" S.A.E. thread, so you could use a bolt if you can find one fully threaded and cut it short enough to fit. Any proper size copper or aluminum sealing washer should work.

Yup, reply #2 is right, it's the neutral safety switch.
Reply #4 is correct industrial version, it's the only one with an external dash light.
