The original Polaroid flashgun #268 was designed for disposable flashbulbs. These flashbulbs could only be used once and were not produced for a long time. The only option to buy them would be ebay, garage sales, etc.
Sure, it's possible to use a modern electronic flash with Polaroid, but it's not fun, I wanted to preserve the authentic look. So I got myself the original flashgun (luckily this thing doesn't have any collectibles value, I got mine for $5 on the ebay) and retrofitted it with modern electronic flash.
Disclaimer: Danger, danger, high voltage! This device produces a potentially dangerous high voltage even after the battery is disconnected. If you managed to kill/injure/scare yourself, your GF/BF, buddies, pets, parents, etc. I am not responsible for it in any ways.

Electronic flash from the disposable camera. I got this, although anything similar should work.
I kept the same schematic as it was. I definitely drew it somewhere, but can't find it. Fortunately this PCB is so simple, you shouldn't have any problem making the schematic of it. Connectors on the board are also obvious:
The PCB was too big to fit into the case, so I split it into two smaller boards:
Rest of it is just wires to make an original schematic.
Hot-glue everything together!
It runs of the single AA battery
Done

Electronic flash from the disposable camera. I got this, although anything similar should work.
I kept the same schematic as it was. I definitely drew it somewhere, but can't find it. Fortunately this PCB is so simple, you shouldn't have any problem making the schematic of it. Connectors on the board are also obvious:
- battery holder - AA battery
- metal tab switch - power on/off
- black and red wires - trigger (sync contact)
The PCB was too big to fit into the case, so I split it into two smaller boards:
- Cut-off a piece of the original PCB (around the charge transformer/transistor) to make a main charging circuit. The diode is not on this board, it is inside the heat shrink tube and soldered inline with the yellow wire (which is connected to the "-" of the main capacitor).
- Made a tiny trigger PCB (it has only HV transformer, capacitor and resistor) on the tiny piece of the perfboard. Neon lamp is wired outside of the board with current limiting resistor inline with the purple wire (the resistor is inside the heat shrink tube)
Rest of it is just wires to make an original schematic.
