Hollow IAB's- Do I Have it Right?

[johnrtse]

Here are pics of the only two hollow back IAB's that I own. I picked up both from the Estand last year.

I am really starting to appreciate the extra detail on these hollow backs as compared to their solid brothers!

I'm pretty sure the left one is a 2nd type Daisy, while the right side is a BH Mayer. Do I have it right?

I would say Frank & Reif on the right, but except for that, all okay!

Left: Daisy made from zinc

Right: B.H. Mayer made from zinc
