I have a 1931 Ford model a cabriolet 68-c. It has a trick vacuum wiper but it doesn’t seem to have any model embossed on it. The vacuum intake is on the right as well as the on/off switch. I bought a “universal kit” to rebuild it, however, is isn’t made for this model. I wish to know the model and if it is standard to that year a make model a?
I will try to include a pic of at least one that looks similar
Spelling check came up trick rather than trico.
Thank you in advance
