particular steel?

Oh. :-)

I didn't know that.

I just finished shovelling the path [1] to the shop today.  I'm not even
going to *walk out there* for MacH's HB tonight.  But I'll look by 'n
bye.

Ah yes, so *much* has gone that way.

[1] Don't get me started on "winter". A typical NS winter is mostly
    open. Maybe a couple of big storms in Jan or Feb, usually melts or
    rains off in a fortnight.  There's between 3 and 4 feet of snow on
    the field right now, a foot of which fell this past week.  The
    back yard is wedged between 10' plough banks.  I'm actually going
    to have to plant my potatoes in *dirt* this year because I
    couldn't get into the field to spread seaweed, even with a 4x4
    F-250.  The plan was to put the new mods to the A&O hammer through
    their paces this winter.  But the diesel is half buried and the
    snow is up over the anvil.  Feh.
