Nice work Mike !
I just thought of something .If you or anybody is looking for these . Here's a goody from the past . At one time , I believe IDEAL toys did this car in about 1/8 scale . It was a toy yes , But the proportions were dead on even down to the headlight screens .
Now that toy even had an engine you could remove and " Repair " . It too was quite nice in that it was clear and if you " Fixed " it right , all the goodies inside moved like they were supposed too !
I would imagine if one was found It would be up in the stratosphere as far as price , especially if it was complete with the tools .Why you could take the nuts off and change tires too !
