This reconditioned and cleaned soda syphon/seltzer bottle was originally marketed in the period between 1934 and 1955 and was made with a high quality hand blown Czech glass body, covered by a braided steel mesh coat for safety.  It has an chromed collar and, unlike the earlier Type C, the CO2 capsule and key do not need to be left in place during use.    This item has a mesh and glass body with the alternative wide, flat, base built in (possibly for added stability).  As with the other variation, the mesh is made from chrome plated steel wire.  The head features the slightly rarer screw on dust-cap covering the CO2 charging feature, rather than the cap-on-a-chain more commonly found.   (The replacement top cap is fashioned from highly polished copper and does not display the AcquaSpumante logo.)
