I would honestly date that around 1924. Dovetail front fender. One piece trussrod, the fork looks like a regular westfield fork to me, I cant tell if the ends are welded or removable to the front axle, crossbar handlebars, most likely not a split bottom bracket, definitely the correct rear dropouts, seat looks legit, stem is wrong, cranks look right, Im not an expert but I do have a photographic memory. I studied these for about a week. I was debating on buying a bike that looked like an Indian and was not sure. It turned out to be a Pope. Same exact frame and fork for the later year Indian but not an Indian.
