Bob's Space Construction truck Series by S.S. Kresge

Hi Woodsy,

I came across, and purchased off of Ebay (new toy to me) a space construction truck vehicle which appears exclusive to S.S. Kresge stores.

By the price tag, probably from late 60s. I could not find anything about it on the blog. It's friction powered. There appears to be three vehicles in the series.

Made in Hong Kong. It's similar to the more common Tomy Space Explorer (battery op) series of construction vehicles that's been discussed several times on the blog. 

Any info? 

 Pics attached.

Thanks,
