Keil Kraft wood wheels?

[Stew]

Hi all.

I was looking through an old mag and noticed a Keil Kraft advert, and in the blurb it mentions that some kits were available with either rubber wheels, or wood wheels. The models mentioned with this option were the Scorpion and the Junior 60.
Does anyone have a picture of these wood wheels?

Apologies for my ignorance, but was the J60 released as a kit initially, or just a plan? I have a hankering to build a fully original Free Flight version of the J60 with a sparkie up front. I have a copy of the early plan, just need some info on the details.

Regards

Stew.
