Ok it is definitely a hitachi fly wheel and i believe it says f-120
on it. Dont know if this means anything to you?

F-120 means it's a Hitachi.
It can still be a flat or retarding or advancing flywheel.
You should see the mechanism trough the gaps of th eflywheel.

If there is a mechanism, you need the high condensator if not, you need the low verson.

HI waynus, ive checked and all there is is a pair of
parralell coils a contact breaker on the left and
a condenser right. Sound right? So low condenser needed?
You know a part number?

That's the correct layout of every 6v ignition plate :D
Can you measure the height of the condensor?
Then I will check with my spare parts if it's the low or high version.

Haha :) i wasnt sure if you should be able to
physically see it.

Yep, that's correct.
If you have the flat type Hitachi flywheel (which I think you have) it will be the low one (normal height)
But the faster Hitachi type uses the high type.

If that's been measured with the connection piece (for the wires) included, you need the standard Hitachi condensor.
(lower, regular version)
