Under the crank, On the front tube or on the back drop out.

I checked all 3 places and I don't see any numbers. I took some more pics and will post in a minute

If the number is on the drop out, it is going to be on the drop out, not on the inside of the chain stay.

like so:

There isnt any numbers in any of the places. Does that me they were ground off or filled?

That's a schwinn straight bar. Use paint remover under the BB shell until bare reach bare metal. If its not there try it on the back. Numbers are probably covered by the black paint.

I'm going search for what year the bike is but if someone knows off hand, let me know
