The one shown by Badger has an unusually fine finish on the action parts, but the butt socket doesn't appear to have been scrubbed clean before the application of the "E-X 2". Probably will have to see the various small markings in more detail to hazard any more guesses. The beech stock does seem somehow atypical, though.

Can't make out enough detail in the remaining photos on this computer to go much further at this point. Big screen on the 27th instant- hopefully!
