I have a bottle of Lubal also. I don't know anything about the company or the product.
But I do know that mine has the "I" within a diamond superimposed by an oval Owens-Illinois trademark on the bottom. They stopped using that trademark in 1954 and went with just the "I" within an oval. The digit(s) to the left of the logo is the year the bottle was made. Often it is only the last digit of the year.
The postal zone system was started in limited areas in 1943 and 5 digit zip codes were started system wide in 1963.
The combination of these 2 clues point to my bottle being made in 1953 since it has the pre-1954 O-I logo and a 3 to the left of that logo plus it has the single digit postal zone on the company address like yours.
