Unused Vintage Italian Red Anodized Aluminum Syphon / Seltzer Bottle by Gimas for Martini and Rossi

Unused in box red anodized aluminum syphon/seltzer bottle manufactured by Gimas for Martini and Rossi (ca. 1970s, Italy). Likely produced as an advertising/promotional item for Martini and Rossi, given the original company packaging.
Does not include a charger, which are still available for purchase today, but includes all other components (syphon has never been removed from its original plastic bag and is in perfect condition).
Martini box shows shelf wear consistent with age.
Box dimensions: H: 13.5″ x L: 6″ x D: 4.13″
