    Keystone Details is now taking orders for the N Scale PRR 3768 Raymond Loewy designed streamlined K4 conversion kit for the Bachmann K4 at the link below. The first ten kits will be numbered in the order of purchase. kits one (me), two through nine have been spoken for.

    Due to unforeseen circumstances, the decals will be mailed separately when I have them in my possession.

    Keystone Details announces its first locomotive conversion kit, the PRR 3768 Raymond Loewy designed streamlined K4 boiler and tender conversion to fit the Bachmann K4 (not included).
