If memory is correct, the cog with the inner circle differs from every vehicle-based cog in the AdMech/primaris/knights line. Usually there is no circle in the center, but a skull. 12 teeth instead of 8, and teeth exactly at the top and bottom (to make painting harder) instead of rotated to this easier position.
Also, the generator housings (big and small) are always designed the same way - round, with recessed nuts, not with a separate outer ring with nuts on top. For reference, see Onager or Redemptor. Not familiar with Fantasy stuff, but might this be from one of their steampunky factions?
(For the record, it's 'jif'. Just saying.)
Jraphics Interchange Format?!? Nah...
