I'm not sure, thats the only markings inside it. If I had a tiny camera on some kinda crookneck thing, I could take pics of the inside of it to show you the construction method of it. It's AWFUL. It's NOT made properly. The wood they used for the top and back is too thick and heavy to ever get a decent sound. The neck joint inside is just... I don't even know how to describe it. "Tragedy" is perhaps a suitable word.
It's probably a good thing that it was made with the wrong materials. It's kid sized I guess, and so it was built to stand up to the abuse of a destructive little kid. I remember getting mad and swinging it like an axe and smacking my bed mattress with it many times. Or just pretending to be a rock star like Pete Townsend smashing a guitar. A "real" guitar would've broken under that abuse. The cracks in the back are not from such abuse, that's from drying out and splitting while sitting in the dusty closet for the last 20 years.
It's possible it could be something made for Sears & Roebuck. There used to be the
old Sears & Roebuck building in East Atlanta. From what my mom told me, her mom used to work there for a time. And from what my dad told me, his family shopped there every now and then when he was little. Today, it's still there, and for a while it operated as Atlanta City Hall East, before they finally sold it to a bunch of dirty hipsters who turned it into Ponce City Market. But I think that's where he said his dad bought it from was the old Sears & Roebuck store in Atlanta. Not sure if Sears themselves actually made it, or maybe Kay or someone else was the builder. From what little I've read about Silvertone and Kay history, it's very confusing and several different companies were making guitars under several different names at different points. Identifying a specific year for some of them based on appearance alone can be as difficult as performing hemorrhoid surgery on yourself with a dental mirror and a butter knife.
You're picturing that now, aren't you. You're welcome.
