Jackpiner serial number question

[Paul Danik]

Greetings,

   The Jackpiner that we just picked up in NY has frame and engine serial numbers that surprised me. The frame number indicates a March of 1972 build date, 7 20354009 with engine number 2-5200083. I know a number of you have early Piners and I am curious if any of them have either March, April or May of 72 build dates, and if so what the serial numbers are on the frame and the engine.
   This machine has a different decal on the tank that I think is original, but I am not positive. It is different from any I have seen before.  Under Penton is has Jackpiner in very, very small letters that is quite different from the usual Jackpiner decal with 175cc included with it. Do any of your machines have this type of decal?


Thanks
Paul
