I have many flashlights of that type.
In origin it was powered with 3R12 4.5 volts battery and bulb was 3.5 volts 0.2 amps E10.
Your flashlight was made in Yugoslavia or later in Croatia in factory ‘Croatia batteries’.
That factory made a few types flashlights for Varta Gmbh.
I modified it many times.
One easy modification is to use Nicelite NL340 led bulb which have E10 thread and work with voltage 1.5 - 9 volts and give about 50 lumens. I have powered it by two paralel samsung 18650 2×2200mah from laptop battery and charge it with TP 4056 module which give 1amp charging current and have discharge protection which kick in about 2.5 volts.
You have space to put it in case without problems and eventually you can add module which converts it in powerbank wih USB A output.
With this setup battery life is more than 24 hours and light from this led is almost stabilized in voltage range from 4.2 to 2.5 volts
That is a nice little light, with a great looking metal case.
I love the red case! Thanks for sharing your work. It’s a very cool light
thank you all
