Normal 261 locos have the steel "peened on" gear, which is re-usable. This looks like the later solid spoke wheel w/ cast on gear & wrap-a-round blackened rim. This same wheel is used on loco #'s 263, 264, 265, etc. They are not currently available, but new molds are in the future for these wheels and the 'thin rimmed' version. Harry
P.S. MTH's version " DOSEN'T FIT".
