Lightsaber with gun attached ? Ulysse (s) 31

I still find things I never knew existed, even of my favorite series. This lightsaber/laser pistol belongs to this category. Somebody said the lightsaber was a more elegant weapon for more elegant times... now attach a laser pistol in the handle and you are ready for the Gods of Olympus !

Ulysse 31 saber, A.G. Excominsa, Spain, 1982

Simple toy, water squirter thing, I guess to be sold in Spanish newspaper kiosks or beach stores, hanging from the ceiling with hooks or something similar ? Exists also with yellow handle/gun.

No marking on the toy, only on the card...

For scale, with a plastic Popy figurine
