Ive been making tripods for years and have been very happy with them. But, an early camera really requires a tray style tripod, just to keep it 'kosher'. Nothing spoils the look of your 1850's camera more than attaching it to the top of a bogen or minolta tripod.
Heres the alternative. This design is so simple, and SO strong, but still lightweight and "old looking". I honestly thing I could sit on top of this thing and be supported. strong.
The camera works at 47" high or thereabouts, and the top tray can be built to snugly fit your camera. Legs are red oak, linseed oil finished, the top is 1/2 inch birch ply with mahogany edges.
