Social Networking for Fashion Doll Lovers
I don't know, but try this lady who collectors vintage skippers, she has a blog you can ask her.
I know nothing about vintage Skipper heehee, but I did some googling and it looks like there were two Skippers with the markings you posted. I personally think you own a 1975 Skipper Funtime ( 7193 )
Unfortunately this source is in Dutch, but I found the same info on other websites as well.
