Here are examples of Reb Reuvens csav, the above is a typical vav he wrote. And the additional pictures below show this as the majority of his vavim.
But some of his vavim [examples below], the top part of the rosh barely extends left past the regel. If looking at the vav in general, it looks as the head and foot are one natural continuation [kav mashuch], and only the lower part of the rosh is extending outward. These resemble somewhat the vav posted by Dovid before.
