Interesting enough, have seen these imported in the 1980's to 1990's from India and Mexico and they weren't as well made as the originals. The paints they used on these were so strong they would have killed any bird in them. How many doors does yours have?
If it is a true Victorian original...it would be worth boocoos of $$$. But the coloring seems "newer".
One of these that would need an in person inspection. Could be a reproduction but still worth some money. Unique with the pull out tray which indicates it is a functional one?!
But, for grins....here is a picture of one that sold at auction within the past 10 years for $400 and an identical one for sell on ebay for $3,000 currently. I would watch it. Don't believe it will go for that.
