I recognisize that frequency counter!

Here are some of mine:
The 3440 that I recently re-capped and cleaned up.

A 3439 that worked for a bit when I first got it but then got flakey; it doubtless needs recapping at least.

A pair of 3470X's from eBuy; both need work (caps, etc.), but they're low on the priority list. I need to find a manual for the display section at least, and they don't seem to come up often.

Workhorse handhelds; the 77-II I bought new 20+ years ago now IIRC, and I snagged a pair of the 27FMs from our favorite wallet-draining website a few years back when the .mil apparently surplussed a bunch of them. Got them for less than $50/pop with cases, leads and HV probes. The second is squirreled away upstairs and not readily at hand.

The ugly looking 3490A on the bottom came from Apex Electronics; I got it when I was out that way this past August. To my great surprise, it fired right up and is accurate to within a few mV compared to the Fluke 8845A at work. Other than a slightly dim digit it seems pretty healthy. The prettier one on top was bought non working for parts on the 'bay, my intent being if I can't fix it to swap enclosure parts with the working one to make it look less like it's been through the war.

The 3456 is another eBuy parts/not working unit I got for a song; haven't yet dug into it to asses its condition yet. The frequency counter beneath it is another fix-it project; I think there's something amiss in the front end.

This pair of 3440As also came from Apex; according to their property tag stickers they were delivered to Bendix 50 years ago in August - both have asset stickers on the back dated 8/65. I'm assuming that the caps are dried out. The display on one counts randomly; alas the second will likely end up a parts mule as it's missing a couple of circuit boards, so I haven't powered it up or swapped boards about at this point.

And last but not least, another purchase from the auction site. This is the meter I used in high school, one of the labs being to draw the damned thing along with its schematic and make up a bill of materials for it as well, with component sources and prices. It sucked at the time, but little did I know that the knowledge would come in handy 20 years down the road. It of course had a dead, corroded battery in it, so there's some cleaning to be done, but it otherwise works well.

I have some more old HP boat anchors that were recently acquired from an estate, but they're not yet fit for public consumption - they spent ten years in a musty basement.
In case it wasn't evident, I have a thing for nixie displays, and to a slightly lesser extent the little dot-matrix-y LED ones HP used to use.
