Today it's been a couple of pens that got written dry (plus one yesterday morning):
Pilot Metropolitan, M nib, finishing a fill of Robert Oster Charcoal, which had already been diluted) -- that pen has been flushed out.
Parker 51 Vac, EF nib, which (finally ) ran out this morning of it's diluted refill of vintage Quink Blue this morning while I was doing pages. That will be the next to flush.
And then from yesterday, the Sailor Pro-Gear Slim, zoom nib. Trying to decide if I'm going to refill (didn't have time on Tuesday) with Iroshizuku Yama-guri, refill with distilled water, or flush it out entirely.
The green 45 I picked up at an estate sale company's warehouse sale a few months ago is probably next on the block after those -- I'm still working with the reconstituted (and now diluted) ink that was in the converter when I bought the pen, but it's still pretty legible (I think it might have been something like Quink Blue Black).

"It's very nice, but frankly, when I signed that list for a P-51, what I had in mind was a fountain pen."
