Hi all,

Simple question really are the knobs shown in the attached picture original or not?
When I brought the set I thought not but, I have now seen many others with them I'm now not sure.

Thanks

Hello TYJ

My B40c has slightly different knobs to those. Mine are like this i.e. flat topped with a groove in the form of a circle in the top. Which version of the B40 is yours?

They look like Eddystone knobs. (TYJ)

John,

It's a B40c, presumably like yours, and I expected "grooved" knobs however lie I said I've seen several fitted with the smooth type.

Hi

Certainly looks like a pair of Eddystone 'Elephant foot' knobs to me too,
but a simple check would be to take them off, and check the underside.
I've just looked at a plain one (without the pointer), and it's marked
Eddystone Radio 3146P in the recess near the middle.

Kind regards

Dave,

I'll check that, if I can get them off as there is little left of the grub screw.

Thanks
