Might be an early version,the rotor does not have the square plinth where the bail arm attaches and I can't find a serial number.

Thanks for that,

Holding the reel with the foot in the air the handle is on the right,Mitchell script is above the winder and appears to be upside dow,I have 2 other 300/301's and whilst they are right hand wind the Mitchell script is below the handle and right way up.

Hi there,

I've come across a very shabby 300 reel that has brass screws for the side plates and the Mitchell name is above the handle and appears upside down,any ideas?
Cheers.
