I've got two wico rotary joysides that came with my cab.  They are 8 way/12 way rotary's.  They have yellow ball tops and have leaf switches
I bought my cab pre-gutted so I'm unsure how well they work and don't really have a way of testing (unless someone can tell me how.   
I'll post some pictures once I get home tonight and pull them from the cabinent.
I'm looking for lots of stuff so email me your trades.  I'm just starting to convert my cabinent for mame so I need pretty much everything still 

You can pm me or email me at lkstitch@ucalgary.ca
thanks!
