I posted the whole page, the top camera was the Acme a field camera
You can have higher resolution images from the other adverts if you want them, they are all quite different angles and higher quality than the 1928 image. The 1939 image show a camera tripod mounted, with it attached via two tripod sockets.
BTW the APUG member who sold the 15x12 then had his second for sale, did you buy the first from the UK ?
Yes, I bought it from the UK. I would have liked to buy the fully restored camera, but it was NOT in my budget at the time.
