2MB pots on ebay

[miha]

So after searching for the Sharkfin "rez" pot for some time now, I came across this http://www.ebay.co.uk/itm/2pcs-Potentiometer-Pot-B2M-2M-Linear-shaft-15mm-/150592219091?pt=UK_BOI_Electrical_Components_Supplies_ET&hash=item230ffee7d3
I hope it helps someone with their build, but I am also interested if anyone has any experience with these pots and if they are what they're supposed to be

Cheers
