Following BB's postings I'm really interested in the Stinson though it's unlikely I shall get my hands on one now. This old report is the next best thing:
Pirep: Stinson L-5
I particularly liked this quote:
The ambulance models also have one of the more hysterical military placards you'll run across. It states, "Intentional spinning with litter patients is prohibited." Makes you wonder what ambulance pilots had been doing to fight boredom when returning with a casualty, doesn't it?
