Looks like antique oil in there, anyway, so be good to drain and flush with diesel or kerosene, after you get it in gear, fun it for a short while with no load, and refill. I presume you had the top cover off, shift fork not in shifter groove. If not had the top cover off, shift rail could be clogged or rusted.
