Stunning Amberina Carnival Compote

My apologies for the upside down photos, can't seem to get them flipped. They were right in the file before I loaded them?!

Found this neat piece at a local Red White and Blue Thrift store. Passed it up first time but it was there the following week and I couldn't resist. I know very little about old carnival and I believe this to be quite old. It is 7 1/2 " tall and the bowl is 8" across. The base is 5" wide.
The base shows it was a 3 part mold according to the seems I can find. Appears to have been stretched and slightly twisted. The stem has a slight twist in it. Base is yellow and the color changes to red as the stem nears the bowl. Bowl appears to have an iridescent treatment inside and out with and satin finish and " alligator " pattern in it. I don't know if this was intended or from age.
There are no chips or scratches but does have some straw marks etc . Consistant with old glass. There is one fissure on base but I don't believe it is a crack as much as an age thing. ( there is no bruise or damage to the area)
I would love to know anything about it if anyone can give me clues so I may research further I would appreciate it.
