Looks like that's actually from 1992 rather than 1983 - 1983 is listed as the date that the shuttle was copyrighted, as it originated in Return of the Jedi which came out in 1983. If you see the other year, 1992, which is next to it, that is more likely to be the year it came out. However, having said that, that shuttle is a thing of beauty, I've always loved it, so it's an awesome model regardless of its year. Unfortunately I don't know what it's worth, but I'd be interested to know!
I seen the 1992 ! lol and edited the Title. I just used my phone to scan the barcode. 49.95 on Amazon. lol
