I found a few of these knob/shafts, Taito part# 998675. Used on Space Invaders II cocktail cabinets and probably others that used that style cabinet. About 3" long. some minor scuffing on the knobs. 

All NOS parts or artwork are the real deal - new old stock from their respective manufacturer - unless otherwise noted.

While parts/art are new old stock, that does not mean they are perfect. Please look at pictures closely. 

I will try and point point any major flaws I find.

Most artwork will ship loosely rolled or flat folded if that is the ways its been stored for all these years. 

I do combine shipping and any major shipping overcharge will be refunded.
