Help with rick 4001 plans

Don't think you'll find any.

Ric is known for aggressively defending its trademarks. Much more so than the other major manufacturers.

Best you can do is find one in real life, or at least a photo on the Interwebz, and draw out your own plans from there.

 

I saw this on eBay. Might help you...
