I had one of those and it was quite nice. Went with my 10/12FT/16 Luddie microkit. [img]http://black.net.nz/drums/littleLud1.JPG[/img]
I paid $117.45 new in 2003 at a drum shop in California. Must have been old stock they wanted to clear? The snares (if not the full Rocker kit series) lasted until the 2000s.
I've seen them misadvertised used on eBay as Ludwig Classic even though they lack the keystone badge. They have a maple inner ply and basswood outer ply (according to Rob Cook's book) and the same lugs as the Classic ones, which doesn't help with the confusion. I've seen them sell from $68 to $170 (misadvertised as Ludwig Classic) on eBay, but haven't looked since 2009. Wonder what they fetch these days?
I sold it when I scored a 1959 Jazz Combo 3x13 which is even nicer.
Here is a new one on eBay now:
