All About Pocket Knives

Hey guys,
I'm needing some help with ID, age and possibly value on these little colorful girls.
Any information would be greatly appreciated.
They are not mine, I'm just helping an acquaintance out.
Looks like a sowbelly pattern to me but I'm not sure...

I can help you with that some. I have had that model and traded it . What a dumb thing for me to do.
It is a sowbelly . It was produced in the late 1980s all the book says about production numbers is rare. You probably know what the handles are"End Of Day" Parker list them for $125.00 in 1994 but the last one I sold on EBay sold for much less,I know it sold for less than $60.00 that was last year.
I would love to git one like it back if your friend ever wanted to sale one please let me know.

Thanks for the info.

He does want to sell. I'm just waiting on a price decision.
