They look like prewar drop centers. They were on the majority of bikes after 1937 or so.

Don't look like clinchers but don't know how you can tell pre war from those awful pictures, hard to see but spoke holes look mors off set ( left to right ) which is not to common, seems like most USA made rims spoke holes are more in line?

Prewar Lobdell flat top rims also have that heavy offset. Gary

I have seen some rims stamped “M.O.” indicating Murray Ohio; perhaps look for some stamping(?).

Looks pretty much like the one's schwinn used imo
