Does anyone have a 067-0521-01 that they don't need anymore? I see a couple on the famous auction site but the prices seem excessive. (even compared to recent historical pricing)

Wow! Three hundred bucks plus shipping. I have noticed a substantial increase in price for 500 series on eBay, but didn’t know how much. Good luck in your search.

I have not seen the history of these fixtures, the TU-7, 1M1, and 067-0521-01. I would like to believe the products developed out of in-house test fixtures used to initially calibrate new units, or in repair to test customers oscilloscopes before shipping them back. If anyone has some information on this, I would appreciate hearing about it.

I would think that very possible. HP developed a three-piece VTVM calibration system for use in the factory and by field techs. The calibration generator was originally assigned a five digit specification number (a system used in-house) but later released to the public in the catalog with a conventional three-digit plus one letter model number.

Just keep an eye out on eBay for them, I bought a 1M1 for $40 plus shipping and a 067-0521-01 for $120 with free shipping a few months ago. They do come up cheap every now and again.

Ditto. I found a TU-7 on ebay for a reasonable price on ebay awhile back
after searching for several years.
