Hello this is Paul from Parker, Colorado. I have a ton of old legos from when I was a kid, all sorted and ready for my 6 year old to play with. I have a set of red and yellow Techniques. If I remember correctly both were some sort of race cars.
I also have an early eighties police and fireboat. Both I found instructions for. Still looking for the techniques. I think I found some old pictures from Christmas when I was a kid. I might zoom in on the pic and see if I can find the model number.
