There's a slight chance the value is stamped on the pot metal case.
If its 250k and you put in 500K, you extend the LF range of the notch by
a factor of 2 and make tuning more critical. If its 500K and you put in
250K you raise the lower limit frequency of the notch by a factor of 2
but make tuning a little easier.
In circuit, check the resistance with the pot all the way to the LF side.
They last page in my printed manual says there's a parts list, but I've
not yet found anyone with a Corsair II manual having that parts list.

I need to replace a fault "Notch" potentiometer on my CorsairII. It's
dual-gang, and mounts to the IF/AF PCB as well as to the front panel. I
can't see anywhere on the schematic that tells me its Ohmic value, or
whether it is Log or Linear.
I wonder if anyone happens to know the details. I'd prefer to obtain a
replacement before pulling the radio apart, otherwise I could just
measure the "good side".
Thanks,
