Vintage Clear Glass Bottle with Embossed Markings

This is a small, clear, colorless glass bottle, likely used for pharmaceutical, cosmetic, or sample purposes due to its compact size and design. Its physical form is a sturdy, rectangular body with slightly rounded edges and broad, flat sides, culminating in gently sloped shoulders. The shoulders smoothly transition into a well-defined cylindrical neck that features continuous screw threading, indicating it was originally sealed with a screw-on cap, which is currently absent. The bottle's construction is consistent with mold-blown glass manufacturing, as evidenced by visible, faint vertical mold seams along its edges and the distinct embossed text and numbers on its surface. Prominently embossed on the upper front face, just below the shoulder, are the characters "3 II" – potentially indicating volume, a mold number, or a product code. Along the very bottom edge of the front panel, there is additional, less distinct embossed lettering that appears to begin with "SAMP..." or "SIMPL...", possibly an abbreviation for 'Samples' or a proprietary brand name like 'Simplex'. The bottle is in good observable condition; there are no apparent chips, cracks, or significant abrasions. Some minor dust and superficial wear are present, common for an artifact of its age. The glass maintains its clarity without significant cloudiness or sickness. Based on the screw-top finish and mold-blown technique, this bottle likely dates from the late 19th to the mid-20th century, typical for utilitarian glass containers of that period.
