Hi
I see these vases are now being attributed to Mandruzzato - lozenge shaped base and top, round front and back, textured sides (slanted)
I see the company is indeed selling these designs ref their website. The date given for the company’s expansion into vases and bowls is 1975 onwards.
I bought these from a source who says they are 1970s and am wondering if the company was making them at that date - mine are certainly not modern from the ware to base.

Are there any other companies that made this type of vase?
Also note the difference in aperture with my two vases - one is smaller and rounder than another - is that normal production for Mandruzzato?
