Pilot lifeboat

Unfortunately, I was unable to identify the model or aircraft from which this inflatable boat comes. All I know is that in order to inflate it, you had to unscrew the gas cylinders (the place for the gas cylinder is in photo 6) which pumped the pontoon in a moment and in case the air started to escape from it, you could seal it with a patch that was included in the set and then with a hand pump inflate air (Pump shown in pictures 7 and 8).

I saved the dinghy from being dumped during the holidays.

If anyone can identify the pontoon model or the plane it comes from, please write to me in the "Contact" tab.
