Check some of the bolts and see if they are imperial or whitworth. That would help narrow down things.
Under the Mendenhall Order of 1893, metric standards, developed through international cooperation under the auspices of BIPM, were officially adopted as the fundamental standards for length and mass in the United States, though some metric standards were used in practice before then. The definitions of United States customary units, such as the foot and pound, have been based on metric units since then.
Standards for the exact length of an inch have varied in the past, but since the adoption of the international yard during the 1950s and 1960s it has been based on the metric system and defined as exactly 25.4 mm.
Even today, over a half century since the UTS superseded the USS and SAE series, companies still sell hardware with designations such as "USS" and "SAE" to convey that it is of inch sizes as opposed to metric. Most of this hardware is in fact made to the UTS, but the labeling and cataloging terminology is not always precise.
WTF could be more "Imperial" than Whitworth? What empire , Evil, Galactic, what? This "imperial" BS needs to die, as did the british empire, 70 or so years ago.Any system based on English or inch measurements is "English", regardless whether it be UN, USS, SAE, or any Whitworth( BSA, BSF, BSW, etc. It is "metric if based on S.I. whether any European or Asian version . No empires need be involved.
