Had a great day with my new friend from Alaska, who contacted me through IFI some months ago about a visit to NZ. I took him out to The Tokomaru Steam Museum http://www.tokomarusteam.com/ for a look at a fully operational steam set up. Here's some pics of a couple of steam hammers and a big old Massey (10 hundredweight I'm told). I'd love to get some more info on these hammers, for the owners please.
Thanks for looking, Jason.
