It is a Cub Aircraft Company J-3 Prospector
The easy way to tell is by the "arrow " instead of the standard Piper "lightening bolt"
Also, most of the Prospectors had Canadian registration that started with CF-B_ _ . The other Cub pictured is a US built one.
Cub Aircraft Company, which was located in Hamilton Ontario built 139 Prospectors before the Dope Shop burnt down.
They had no Cub emblem on the tail but I have seen some that had the "Prospector" name painted in the same location.
The factory was located in the city and they also had a hanger at the Hamilton Municipal Airport on Reid Ave. That was the second airport in Hamilton.
Mt Hope is the third.
There are still some Canadian Prospectors around.
FYI they cannot be sold to the US because their type certificate is not recognized in the US
The first " Cub " in Canada was CF-ANT, an E2 Cub which I am allowed to fly when ever I want
