Bally Block Co Counter Tops

Hello, I’m renovating my kitchen after being in my house for 18 years. I found your logo on the underside of the counter tops and wondering if you could date the counter tops, by the logo, perhaps. I don’t know when the kitchen cabinets and counter tops were installed but guessing 50 or 60 years ago. Now I am going to sand some of the tops in hopes to reuse them. Thanks for any info you’re able to provide.
