Older Jet Planer

[Timmy Will]

Hey guys. Rookie Young buck here.
I am tired of driver across Erie County to use my Grandpa's planer. There is an auction tomorrow close by that advertises a 21" Jet Thickness Planer.
I will try to imbed some pictures. That didn't work so here are the links;

I know it's last minute but I just happened across them myself.
Any input on this? Age/Model #?
What kind of value would one put on this?

First pic #10 Is the back of a JMP13 A 13" planer with a cutterhead that you can put molding knives in. They still make it as far as I know. I had one for about ten year serve me well.
The second looks like a standard four post planer these where made in a 15" and 20" the blue color was used up till 1998 I believe. Then Jet when to white.
