Problem is, you will have to look up what that is compared to US nomenclature. Also, contrary to what I had always assumed, the TR motor?s crank is steel, not iron, and perhaps the Spit crank is as well.<br class=""><br class="">Duncan Charlton<br class="">Elgin, Texas USA<br class=""><br class=""><br class=""><br class=""><blockquote type="cite" class="">On Sep 7, 2016, at 8:07 PM, <a href="mailto:don@dcphotos.com" class="">don@dcphotos.com</a> wrote:<br class=""><br class="">OK so Greg Blake was holding out on me but Duncan spilled the beans!<br class="">Here?s what I?ve found out so far.
