Town Sedans had electric wipers approximately through June 1930. If it has an oval speedometer it almost certainly had an electric wiper. This does not necessarily apply to Standard Fordors. I suspect they went longer on Canadian built cars. The mounting hole pattern was different so you would likely find extra holes in your windshield frame if it has been changed.

The wiper you describe would be a replacement (like most of us have). The Trico wipers originally used had no patent numbers but instead had a series of patent dates. The last date listed found in the circle was in 1925 but I don't recall the month and day.
