There was me thinking April 1st. had come around early, but looking at the tank logo, I think that brand-name probably translates better as 'Two Rabbits'...
Looks like a re-badged Aida. Can anyone more knowledgable on Aida (not hard) confirm that. Double is the correct spelling.
Aida copies for sure but probably Thai made. Double Rabbit is the translation of the brand Hoa Seng. These are common in Thailand. I got one a while back in trade and on the Thai collectors web site there are quite a few illustrated. ::Neil::
