Very nice restoration job! Well done. Those old Defender sets are cool.
I'm curious as to the bass drum size. Is it an even number like 22" or 24"? Also, is the bass drum 14" or 10" depth? The reason I ask is that many of the Defender bass drums were odd sizes. I have a pair of Defender bass hoops w/ wmp inlay and they are 23 inches or something odd like that. I'm not sure why Gretsch chose to go with non-standard sizes back then.
