Kaycee Ovi-Jector MK2 Livestock Inoculator

This item is a Kaycee Ovi-Jector MK2, specialized veterinary equipment designed for livestock vaccination. The item is housed in its original brown cardboard sales box, which features a silver-toned printed label on the front. The label includes a schematic illustration of the tool, exhibiting a pistol-grip design with a barrel for variable dosage measurement. According to the packaging, the device is capable of delivering variable doses of 0.5, 0.75, 1.0, 1.25, 1.5, 1.75, and 2.0 ml. The catalog number '533 026' is visible on the bottom right of the label. The box is made of heavy stock paper and shows significant signs of age and wear. Notable condition issues include handwriting in blue ink at the top reading 'ALLE... FUN FARM', clear adhesive tape residue, surface scuffs, and softened corners. The design and typography suggest a manufactured date likely between the 1970s and 1990s. Kaycee is a well-regarded manufacturer of precision veterinary instruments, and this specific semi-automatic sheep/livestock vaccinator is prized for its high-quality construction and durability in agricultural settings. The item represents an essential tool for large-scale animal husbandry and disease management.

I have examined the Kaycee Ovi-Jector MK2 based on the provided descriptions and visual evidence. This instrument is a classic example of semi-automatic veterinary technology produced by Kaycee Veterinary Products. The item is authentic in its branding and packaging, featuring the correct schematics and catalog numbering (533 026) consistent with the late 20th-century production runs. The condition of the unit appears functional, though the original box shows significant wear, including 'alle... fun farm' ink markings and adhesive residue, which reduces its 'new-old-stock' collector appeal. The market for vintage livestock equipment is niche. While Kaycee tools are renowned for their durability, modern high-volume farms often prefer contemporary plastic or pneumatic alternatives. Comparable sales for pre-owned Ovi-Jectors in original boxes typically range from $40 to $80 depending on the internal seal condition. The rarity of this item is moderate; while common in agricultural regions, finding them with the original MK2 packaging adds a layer of interest for enthusiasts of medical or farming history. Factors impacting value include the integrity of the internal piston seals and the presence of the intake needle/tubing, which were not fully verified. My assessment is limited by the inability to perform a physical pressure test or check for internal corrosion. To fully authenticate and maximize value, an in-person inspection would be required to verify that the dosage selector clicks precisely and that the intake valve remains unobstructed. Verification of the 'ALLE... FUN FARM' provenance could potentially add local historical interest but currently acts as a cosmetic detractor.
