Greetings! Tou certainly came to the right place!
This is a made in Japan (MIJ as we call it) 'stencil' snare drum. These were very inexpensive drums typically manufactured by Pearl or Hoshino and were often copies of major US manufacturers. They are referred to as 'stencil' drums as they were typically manufactured without any identification badges or logos and then sold to American distributors who put their own badge and head logos on them. Therefore the same kit might be sold as any number of different "brands" depending on your geographic location. These kits were sold as the entry level kits at music stores starting in the mid 60's or so with prices far lower than American made drums. They were also the kits sold by major retailers such as Sears, JC Penneys, Montgomery Ward, etc.
This one is a Slingerland knock-off. One of the experts here can tell you who manufactured it. It is a very nice example by the way. There is very little monetary value in these as they were cheap to begin with. Having said that, a lot of drummers have a soft spot for these drums as they started on them in the 60's through the 80's. Also, while the vertical grained Luan shells are generally pretty poor in quality, many here say that they have hardened over time as they dried out and actually sound pretty good now. There is always someone looking for an individual drum to fill out a restored set. Probably the most common colors were blue sparkle and red sparkle so finding someone who might want that particular snare is pretty high. There are also drummers who keep one or two of these types of snares in their arsenal as they are generally not as loud as a higher quality snare so they can be helpful in small venue situations where volume is an issue. Good luck to you.
