Lot of 13 National Electronics Nixie tubes pulled from working vintage Heidenhain encoder DRO units — 12 are NL-5441 numeric indicators (digits 1–9) and 1 is an NL-5442 sign indicator (+/−). These are cold cathode neon gas-discharge tubes in clear glass envelopes with 16-pin bases, manufactured in Geneva, IL (date code 7516). Getter material appears intact on all tubes and no cracked glass was observed; tubes are mounted on PCB carrier board remnants solely to protect the pins during shipping — those boards are not intended for reuse. All tubes were working when removed and are guaranteed functional.

Shipping Costs: We do not look to make money on shipping charges. We only try to cover actual postage and shipping costs. If you feel a shipping quote is too high, please contact us as we may very well be able to do better. The eBay calculator is simply one estimate. On some products we offer Free Shipping to the 48 contiguous states. For Alaska, Hawaii, US Protectorates, APO/FPO please contact us for shipping costs.

Turnaround Time: About 95% of our orders ship within one business day. If you let us know there is a rush we can almost always ship the same day. Freight items usually have a 2-day turnaround time.

Next Day Shipping: We can offer next day shipping on just about all our products even if not shown on the calculator. Please contact us. We usually get products out the same day even if paid as late as 4:00 PM MST.

Customs / Commercial Invoice: We cannot reduce an item’s value on a commercial invoice or shipping document. Misrepresenting customs values is against federal law and eBay policy.

Packaging: We use only the best void fill and cushioning products. We have a foam-in-place system, full crating department, and hundreds of in-stock box sizes.

Freight / Items Near or Over 150 lbs: Many products must be shipped truck freight. We have a loading dock and get very competitive rates with all major freight couriers.
