Victoreen THYAC III  490 Geiger Counter with 489-35 Probe, Test Source and Speaker Working Geiger Counter with probe, speaker, test source and manual reprint. I was unable to test the speaker because the  Type 504 15 Volt battery is dead. The internal circuitry looks nice with no signs of corrosion.  Some capacitors appear to be upgraded (newer mylar dip type) .  Manual includes a very detailed Schematic and parts list. Past Calibration Stickers are another clue this unit has been serviced. WHAT YOU SEE IS WHAT YOU GET. Free USPS Priority Mail Shipping to the Lower USA 48 States. All other locations must pay actual cost of shipping. Thank you for looking, lynnt850
