A firm identification isn’t possible from the information given alone, but one plausible lead is that the camera may be by Lamperti & Garbagnati of Milan. The fitted Schneider-Kreuznach Xenar 180mm f/4.5 in a Compur shutter is quite possibly not the original lens, so it may not reliably date or identify the body.

That matters because large-format folding wooden cameras were often used with replacement lenses and shutters over their working lives. So the body and lens may come from different makers and periods.

Based on the single community answer, the strongest conclusion is: it is likely not American, and an Italian maker such as Lamperti & Garbagnati is a reasonable possibility. To narrow it down further, look for maker’s plaques, stamped hardware markings, bed rail details, focusing mechanism design, and any serial numbers on the body itself rather than the lens.
