The red one has me writing an article for my next website update
And yes, the blue one is a long wheel base AP703 and by engine number is 2nd vehicle made after the red one, mine is the newest of the three with engine number 417 newer and production date of 11/71
The part that is interesting is while mine (with DOT label)has breakers, the other two have fuses which I interpret as Canadian build(no DOT label)
As for the grass, it does disappear rapidly if the Haffy's get restless
