I thought it was 1954 that Packard introduced tubeless tires, not 1951, and that it was pretty much an industry-wide changeover. But that not withstanding, prior drop-center wheels (wire wheels excluded) though not designed for tubeless tires will generally be air tight at the rivets or welded seams, but it's a matter of chance and the percentages are very largely, in fact hugely in favor of them being satisfactory at least as far back as 1938. And yes, if you can locate the air leak at the wheel where the rim attaches to the hub, you can use a sealant.

As to tube size, tube sizes are matched to tire sizes though often tubes will have a range of tire sizes for which they are compatible. So just get a tube marked for your tire size.
