Difference?

OK so I got the one on the left earlier in the month and was told it was an Excalibur by Kai Han. Now I go this other one and it is completely different more modern? so I am curious s the one on the right newer? and the one on the left more vintage? the left one has a long neck bigger bottle and the stand is brushed aluminum with a dome like foot on the stand. while the one on the right is paintied sparkley and has a pressed angular stand like I have seen on other Kai Han's plus the bottle is stubby and has indentations to fit the stands while the one on the left does not.
