Godox makes a couple of electronic flashes with folding dishes if you want to go retro without burning your fingers on flash bulbs.
Godox Lux Senior which is manual or thyristor and the Godox Master Retro which looks like it is either manual or TTL for Canon, Nikon, Sony, Panasonic and Fujis. Haven't used either but have used other Godox flashes and they work well.
The Lux Senior might be fun since it also has a pc sync connection so it could be used on a bunch of cameras.
