I found a couple very similar bottles when swimming a few years ago , mine look identical but are for sanderson porter beverages Toronto , also say frosty beverages too .
pretty sure there 40's early 50's era bottles , as I found mine but didn't pay retail for them , not sure of a price but I doubt there worth much more than $10 each
but if you have any others in that lot your unsure of post them here and we might be able to help id them
