30x100mm WECOM 1968 round (another one)

I bought 2 at the same time but decided to post them separately not to get confused between them. This one has an identical cartridge (except of the top of the ignition stalk inside has no red plug, unlike the other one), but the projo is different. It has a moving aerodynamic blue cone except I am not strong enough to take it off. Can anyone decipher projo’s “headstamp”?
