I've finished the functional repairs and most of the cosmetics on that reversible-back Premo (with the long bellows) and put some film through it this morning. I wanted to make use of the close-up potential of the long extension and I found a toadstool in a neighbor's yard that seemed a likely subject. Had to lie down in the wet grass to pull focus and only one of four frames was well exposed. I need to take a look at the shutter and do some timing tests, but the lens performed admirably. The whole rig is at least 110 years old (they were made from 1897-1903) and all it needed was a brass catch for the rear door, some pinholes in the bellows patched and some restoration of the leather covering. There's a bit of separation in the front element, but it didn't ruin the image.
