Which focusing handle for 50CT*?

[film_man]

Hello,

I'm looking to buy one of these quick focusing handles for my Hasselblad 50 CT*. Does anyone know which one I need? Are they all the same? Will the 80mm one fit?

Thanks.

...and while we're at it, will the pistol grip fit the 501CM? I read somewhere that the tripod plate has been changed for the 501CM/503CW so they don't fit...?
