This is a vintage Porter Microcraft Senior Microscope Lab (Outfit No. 2105) manufactured by The Porter Chemical Co. in Hagerstown, Maryland. The complete set comes housed inside its original blue metal fold-out carrying case, complete with colorful vintage graphics and graphics depicting 'Explore The Invisible World'. The set features a heavy black cast metal microscope capable of 75x, 210x, and 425x magnification, along with various period-appropriate accessories. Inside the case, you'll find slide boxes, glass vials containing specimens and reagents (such as Mounting Cement, Thinner, Shrimp Eggs, Hay Infusion, and Fibrous Specimens), test tubes, a pipette, tweezers, and original literature including the 'Senior Microscope Manual' and 'Secrets of Nature' booklet. Condition is consistent with age and vintage scientific toys. The blue metal case shows light surface wear and minor scuffs. The interior cardboard mounts show some tears, wear, and tape reinforcement, particularly around the manual inserts and bottle slots. The microscope and glass elements remain intact and functional for display or hobby use.
