Search 'systron donner counter' and you get to the Wikipedia article of nixie tue counters, where a bad, but not so horrible picture of a SD 6032? 6052? 4062? (try your own squit-eye OCR).
6052 looks similar, but no N connector (perhaps prescaler option going higher?) see http://cgi.ebay.com/SYSTRON-DONNER-FREQUENCY-COUNTER-Model-6052-6052-10-/230 589920052 -----Original Message----- From: time-nuts-boun...@febo.com [mailto:time-nuts-boun...@febo.com] On Behalf Of Dr. David Kirkby Sent: Friday, July 15, 2011 5:49 AM To: Discussion of precise time and frequency measurement Subject: [time-nuts] Anyone know what this counter is? There's a frequency counter on eBay http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=150631192544 but the photo is so poor it's totally impossible to make out a make or model. I contacted the seller who said he is away from the unit and can't tell me what it is or produce a better photo now. Does anyone reconise this? -- A: Because it messes up the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail? _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
