An original early-70's green P-15 hangs in a local shop which has more pinstripping than I've ever seen for this time period. Flowing pinstripes across the toptube and down forklegs. Was this treatment usual for older (60's) bikes and/or either a custom feature or the striper just felt good that day in the 70's? Both my 71's have only the usual lug outlining and a recent '74 acquisition has the expected none at all.
Also, is presence or lack of dropout eyelets a sure-fire indication of whether a P-15 or P-13?
Didn't the addition of the Olympic Rings on the seatube start with '68 models?
