Does someone recognize this aircraft part?

Very cool, but I think the panel shown might be the control head for the device.

Rather odd that it uses straight-slot screws; most US aircraft uses Philips head screws. British perhaps? Where was it found?

My thoughts as well. I believe the OP was from Holland.
Over the years I have seen some US made aircraft accessories that do have slotted screws in them rather than Philips head. Compasses come to mind.

Is it not an Alternate Air Supply panel and cocks?

Yes, but it seems it's tailored to support this equipment
I work at Yanks Air Museum, Chino, and basically nothing we have prior to 1946 has Phillips head fasteners (originally). Slotted screws abound along with the odd Reed & Prince (Frearson) crosspoint screws*. Truly a PIA. We're currently working on our P-63 and the erection/maintainance manual will helpfully point out the Reed & Prince screws in the procedures as they're not terribly common relative to the slotted.
*A Phillips driver doesn't fit a R&P head very well at all and will likely strip the screw head.

NACA had V-G recorders back in the 1930's. Prior to about 1950, they were dry dampened . That report is about the new oil dampened ones.
As to slot head screws.....They were on airframes, instruments and furnishings. I've got stuff on both my L-5 and AT-21 that have slot head screws, and they were built in the 1943-44 period. The specifications for that hardware dates years prior to that. I don't have the spec number for the ones in the cockpit cover for the AT, but there are over a hundred of them in it, alone.
