I could be wrong but the top one appears to be for an American 6 sided visible, maybe a Milwaukee 6 sided. If you could get a way to photograph the gallon markers that could help.
The bottom looks like a G & B visible. The bonnet, size, gallon markers, all look G & B. The etched cylinder is very nice.
