I was just looking at 4x5 120 6x9cm roll film holders over on the B&H website.
The Arca Swiss #611012 and the Horseman #47022451 appear to be identical. The photograph of the Arca Swiss unit even has the Horseman brand name embossed on it.
Although there is $100 difference in price, are these in fact the same holders? Or do you suppose B&H got their product illustrations mixed up?
Also, has anyone had any experience with these? I used Linhof units in the old days until they got to be so costly. The Calumet unit owned by a friend in the 1970's seemed rather cheesy. Any thoughts about the Sinar or Toyo units?
