My earliest model Deardorff V8 has two rotating tabs to lock the lens board. The hardware is gold painted and it did not have a bed plate and had red leather bellows when I bought it a couple of years ago. This has no front swings and is about 70 years old. It is as solid as either of the two more recent V8's that I have. Both of which have bed plates, a locking plate for the lens board, serial numbers, nickle plated hardware and have serial number of 3*** and 5***.
I would much prefer to have front swings over rear swings. The use of these two movements is not interchangeable. Movements at the lens standard do not alter image perspective whereas movements at the film plane alter image perspective.
