Saw these, quite unusual as I've never seen IN1's without their rather ugly brown bases....

The auction says he took the IN1s off the bases himself. I wonder how easy it is to do?

Hot air gun? Maybe it plops right off.

It's quite a bit of work to pop IN-1's apart. There's a crusty adhesive in the base, and heating / sawing / grinding the base gives off some really obnoxious (and probably toxic) fumes. Smells like bakelite to me.

If any of you are pulling these apart to save money on sockets, please consider your personal health and make your own sockets. I've had excellent results with 0.093" female socket pins for IN-1's and A101's, and you can easily make a 3D-printed-base to hold the assembly.

Looking at an IN-1, it looks like a quick snip of the ends of the pins would free up the leads. Not sure about how much work it would be to remove the base. 

I didn't realize just how dis-liked the brown base is. I guess it is a bit ugly. But the tube has a nice sized digit and sadly, the bad "5".

I wonder if soaking the base might free up the cement. In water or a mild solvent... Shouldn't hurt the wire entry into the envelope, and maybe one could keep that dry using careful positioning.

Funny how the ugly duckling/sad stepchild tube becomes a little prettier without her brown dress.

But still, as a non-mercury-containing tube, the lifespan isn't very long, correct?

Possibly, but as inexpensive as they are -- stock up a whole slew of spares.

I wonder if it would fit any known socket without the brown base? Maybe the IN-18/IN-4 RSH31?

Well it has wire leads, so no. But could be soldered directly into a PCB.
