I have an original Little Petro purchased new in the early 60's.
I have the original brochure.
It runs and I have done the following:
Modified seat...Chain Guard... Nickel plated frame...added plates to out riggers, all work was done 30 to 40 years ago by me.
My son who is 55 rode it when he was 3 yrs old, grandson and grand daughters have been riding it each Christmas.
