Help Identifying Bikes

[dcoultis]

I have the chance to buy a group of bikes but have no idea what a couple of the older ones are. What are these and what are they worth? Thanks for your help?

The blue girls bike is Monark built. Probably early 50s, could be late 40s.

I believe the white bike is Austrian, but could be British made. Probably latest of 50s to earliest of 70s.

Good pics of badges and dropouts would be helpful...and serials.

I agree that the white bike with the interesting tubing is the cool one of the whole lot.

The white bike may have the country it was made in on the head badge, or a decal on the seat tube. If it's Austrian, it was likely made by Steyr/Daimler/Puch. If it's German, it could still be SDP, or it could be one of the smaller companies like Bauer, who exported a fair number of bikes. I have a Royce Union that's pretty similar, the differences between brands is really subtle.
