Hello,
I have a very cool vintage Trico Visionall wiper display give to dealers in 1927, I believe. This is complete as far as I can tell and operated in a way that showed the wipers moving from side to side.
I'm looking for any information on how the display operated. It's very odd with no electrical connections or motor. There is a small diameter air hose barb type fitting the leads me to believe it operated by air pressure. I ran some low pressure air though it, however, it seems to be not made in a way to hold air pressure.
Can anyone provide additional information on its operation??
Thank you.
Dave
