Technical Autolite generator disassembly-Pulley

So I have searched the service manual & Autolite manual & can't figure how to get the pulley off. It does not appear to be pressed on & it won't unscrew-Guess I will try clockwise next? It is mid 50's vintage, 12V.
And yes, the nut has been removed

 

Here's an autolite

 

Thanks Choffman,
That photo did the trick. ChinaFreight had a Gypko brand puller that fit with a little help from the grinder. It was definitely a press fit and the key prevents it from simply being driven off of the shaft.
