What letters does the serial number begin with, the serial number will be either on the rear dropouts or on the bottom of the head tube. Handlebars look 1968/69. 1968 would not have a front fender and have a pogo seat. Seat is wrong for a krate, shifter looks 70-73. '68/'69 would have a straight up shifter. Seat would be white with orange stripe and "S". Listen to everyone, do not paint this bike. Wash it with very soapy water and leave it alone. Looks like it will have real nice paint. Be careful around the lettering on the chain guard and the rest of the bike, wash it very lightly do not use cleaners on them. They wipe off very easily with many cleaners. Serial number will tell the year. Very nice bike. I don't know everything about anything but I am pretty sure of what I posted. I had many Krates in the past but it has been a while. I'm sure someone will correct if I posted something wrong.
