To lighten my load on long hikes, I picked up a 4x5 Galvin. I added some modern niceties like an adapter board to Linhof TK boards and levels on both standards. The other thing I'd like would be a focus scale marked in mm like I have on my Technikardan. When I had a Gowland Pocket View I milled a flat on the solid rail and glued in a strip from a ruler. All the rail on the Galvin is hollow so that's not an option.
Does someone have a suggestion? Also, as I recall some Sinars had a knob that gave the mm's or dof information (never owned a Sinar so my memory may be faulty). Something like that would be an option also. Any ideas are welcome. I have access to a machine shop so machining and fabrication are no problem. Thanks.
