Imperial Debonair

I'm shooting a found (don't remember where I got it) medium format Imperial Debonair. A retro looking plastic camera. Unlike a look down Kodak Brownie this camera has a look-thru viewfinder.  Shoots 620 sized film. This film size is hard to find. I bought a roll online from Film Photography Project store and loaded it up. After 5 shots the film jammed. I opened it up in a room with the lights off. The top spindle had popped off. I snapped it back on, and shot another photo.  Jammed again.  Opened it up, and put the spool back on.   Hopefully I can finish the roll.
