That is a very nice drum..........I know because my wife found one just like it in a secondhand/pawnshop last year. She said there's a Gretsch drum-white-with a square badge on it .....you should go see.
I thought it was going to be a WMP Cat....which is alright.
Well imagine my surprise when I saw same drum as yours........stand and all. I scooped it right away and I like the drum......sounds very 'snare-ish' kind of like the Acrolite.
Congratulations - Nice find! :)
