Anyone got a picture of the pre-war tank panel on an M 23 or M24 or M20. Not sure of the hole sizes for switches etc compared to the ones in an Indian tank he received?

Hi,
I found these, if it helps.
The first one should be M20 and the 2nd- M24.

Noam.

Thank you, but i can't figure out what the bottom thingamejig is?

Douglas,

The bottom indicator is the oil pressure indicator. It is the same gadget that sits on the timing cover of an early M20. The holes for the swith and the ammeter should be 2". I don't know the hole size for the oil pressure indicator right now but it's substantially smaller in size.

The panel with the blanked off hole is not for M group bikes. The blanked off hole was used on the total loss V twin which of course doesn't have any oil pump and consequently no oil pressure. Before 1937 the hole whould be in a different position since a 2" Eureka oil pressure gauge was used instead of the oil pressure indicator.

Regards,
Leon
