i found him on ebay last night. i asked if he would ship intl, to which he said no, so i asked albert who was kind enough to help out.
so for just over $230NZD, i have the forth and final tomix engine for the set. he looks in good shape, with all 4 face masks included. the box is there, damaged, but i only store those. most important thing is no missing buffers or couplers.
will be a couple of weeks before he gets here, and i will of course do a series of better photos and take him to the club for a run.
