There were several models of these cameras made; some had more movements, some less. Those sold as "portrait" cameras often had a little front rise but nothing else on the front standard; it was cheaper that way and the immobile front standard was more stable and less prone to vibration, especially when using the heavy, large aperture and soft focus lenses often favored by portraitists.
I can't tell much from the picture; your camera looks like it once had rise/fall and tilts on the front standard and, if the user thought it necessary to add two bolts to hold it down, I'll bet it had swings and shift as well. It was perhaps modified by a portrait photographer, who rarely use front movements other than a bit of rise or fall.
Look at the picture of Ian's camera: that metal half-round bit on the side of the front lensboard, on the right in the picture, was what Ansco used to control tilt on the front lens panel. Finding one will be difficult I imagine but all it is is a clamp with a knob to tighten it, installed at the middle of the lens board. Loosen the knob to let the lens board tilt backwards or forwards, tighten up again when you get it where you want it. You ought to be able to fabricate or have someone fabricate a substitute easily enough. Google Ansco cameras and you ought to find photos to make it clear.
Swing and shift are even easier: there was a center bolt rising up from the bed, with a knob that tightened against the board forming the bottom of the front standard. It passed through a slot in that board, the bottom of the front standard. Loosen to adjust, tighten to, well, tighten. Look for signs that the bottom piece of the front standard once had a slot about three inches (90mm, +/-) long and the width of a solid bolt, or whether possibly it looks like the old piece with the slot may have been replaced by a solid piece of wood. Either way, you ought to be able to add those movements easily enough. The simplest thing would be to simply drill a hole for the bolt in the center of the bottom piece of wood: that would give you swings. Personally, I can't remember the last time I used shift so perhaps in the name of simplicity you don't need it?
Good luck!
