Looks like a later one with the 5" good years, Lighted 2.5 engine, larger lighting kit etc.. I'll take a stab at it being around 1969 but I would be interested to know the model number and date code on the engine. I would not doubt that they may have run that shroud into 1970 because a lighted small frame that could fit that shroud combination still (H35 or smaller head=smooth top and studs for recoil mount) was very uncommon, probably safe to say that SK was the only one ordering them at that time.
Is the headlight shell stamped PM711 or AP4600? If there is also an SAE stamping under that like M67, it will be 1967-up
Looks pretty dam complete :thumbsup:
