I assume it is called that because the base is curved? I thought it was a early VS 2.
The cabinet is very pretty. I bought it from an antique dealer about 15 or 18 years ago. My hubby thought I got ripped off because I paid like 275 for it but I have enjoyed having it and I figure if I dont want it anymore I can sell it for probably around what I paid for it. Something you cant say about most things you buy.
