eBay Antique Variable Electrical Resistance in Series Testing Box – by University Apparatus Co. I. CONDITION Great. USED. Previously owned. Wiring inspected, but not tested. • Item’s Background – Retired Engineer’s Estate Sale Item, Pasadena, Ca. • Working Condition – Excellent. This testing device appears fully functional and ready to perform exactly as originally intended (with the addition of contact pins, not included). Resistance is measured by adding up the individual values of each internal coil component in series. The total resistance of the system is just the total sum of the individual resistances. • Cosmetic Condition – Shows Well. Normal wear, corrosion free. • Bottom Line – This is a handsome classic Antique Variable Resistance Testing Box at a very reasonable price. II. DESCRIPTION Manufacturer – University Apparatus Co., Berkeley, Ca, USA • Total Weight – 1.93 Lbs., before packaging • Manufacturer’s Stocking Item Number – Not known. • Model Line – Ohm Tester • Age – Vintage, likely 1890 – 1910s. Pre WWI. (est.) • Current Retail Replacement Value – Difficult to determine. Comparable Antique Circuit Resistance Boxes are occasionally available on the internet, particularly on eBay. • Item Weight – 1.93 Lbs., before packing • General Dimensions (LWH) – 7.6″ x 4 x 4.5″ Key Features: • Functionality – Totally old-fashioned, but fully serviceable. (Could benefit from addition of contact connecting pins. Not included.) • Practical Use – In this era of accurate digital-electric Ohm Meters, old fashioned portable Circuit Resistance Boxes may be a bit obsolete, but this unit remains an excellent attractive nostalgic curio display piece. Would look great on a curio display case. • Component Materials – Brass contacts, wire wound resistors, Bakelite pin-contact deck, wooden case. (Not included: the original brass contact pins.) • General Maintenance – This item will eventually tarnish a bit in air, but only slightly. Every 5 years or so, I recommend a casual wipe with something acidic like Tarnex followed by a gentle brush grooming. III. SHIPPING All orders ship within 3 Business Days or Less of payment. (Usually less. I try hard to ship orders the same business day they are placed.) Shipping Factors: • Item’s Actual Weight – before packing: 1.93 Lbs. • Shipping Weight – fully wrapped, padded & packed: 2.2 Lbs. (est.) • Packing – no special boxing or crating is required for this item. Shipping Charges: • Local Pickup ……… $00.00 ….. Orange County, California, USA • United States ……. $08.00 ….. USPS Priority Mail Medium Flat Rate Box • If you need faster shipping, you must let me know before paying. • Upon request, I will combine packaging and shipping for multiple eBay item purchases – if weight, size, and packaging considerations permit. IV. Return Policy 100% BUYER SATISFACTION GUARANTEED – The Best on eBay! General Policy: • Returns Are Gladly Accepted Within 30 Days – if properly packed and received back in their original condition. • Refunds Are Given: As Money Back Upon Return – for your purchase price plus original shipping. • No Hassles or Challenges – You just notify me in advance and then pay the return shipping.
