Riley Kestrel picnic tables?

[sally]

Hello all. I'm really new to this and I'm more than sure I'll be shown the right direction if I'm incorrect but I think I have two Riley Kestrel picnic tables, possibly from a 1968?! 
I'm hazarding a guess from seeing photos of the interior of one that is for sale.

The tables look to be walnut with what looks to be oak surround. There is age related scuffing & light scratches but  overall condition looks to be generally good
I've included a couple of photo's

They are for sale, if any ones interested please get in touch, there are more photos

Thank you all, any info will be gratefully received

Hi Sally,
Don't know what they fit, but they look nice and I possibly have a use for them, how much do you want? You can contact me direct at "[e-mail]"
