I'm calling these components obsolete, but I really don't know...

Anyone familiar with Transitron Components?



How about Hewlitt Packard Components? Looks like these were also used for Harrison, Boonton, Sanborn, Dymec, Moseley, and Y-HP products?



Anyone familiar with Clevite Components?



And lastly, how about Workman Components?

Since this is the place for obsolete stuff, I figured I'd contribute some cool old stuff i found at work. Here are some random obsolete electronic components:


Obsolete Resistors from Workman


Obsolete Semiconductors from Transitron


Obsolete Transistors from Clevite


And what are these Components?

It is Renshaw TS27R

Guys,
How Long Does a Renshaw Probe Last? We have gone through numerous probes in the last year. We break the tips and we break the probes.

I don't know if it our machining center somehow crashing the probes, or if it a software gliche, or the Renshaw hardware is not durable. Any thoughts?
