MINOX Camera & Flash including leather cases (Made in Germany)

These items were given to me by my father, who served in WWII. This camera and flash are in mint condition. Am looking for info on where to buy film and flash bulbs. The camera is 3 1/2" x 1/2" and the flash unit is 3" x 1/2". Both have leather cases that are in very good condition. The camera case also has a 24" silver strap that is attached to the base of the camera with a leather tab that can be secured over a button.
