in my experience very hard to date/identify bottles with only numerical embossing on base. However the “dotted” like base to me resembles 1940s through I guess 60s. They began in the 40s or so to make bases with that type of surface to prevent slipping on surfaces. It looks like possibly a condiment jar to me (mayo, peppers, pickles, etc.) by no means an expert as other members may be more knowledgeable. Regardless, neat find!
