    The owner may be confusing 40 in the model with horse power.
    From the one small picture and from my limited knowledge Johnson offered a P40 Big twin at 13.15hp ( I just got one) and a TR40 Giant twin at 25hp in 1928 and as mentioned above there are probably a few other models.
    If by chance it’s a TR40 it’s really worth a look as those are really uncommon.

    I can do a comparison of the picture with my motor when I get home.
    It looks like it could be a P40 in what appears to be nice condition.
