oops. i meant "number 474..." and "...off the INSIDE of the tubes in a
steam engine...." did/do heat exchanger tubes in a steam engine get cruddy?
or i guess maybe even a stationary boiler.

i went to china in 1986 and they were still using steam engines there. it
was marvelous to ride through the terraced hills of china on a fire
breathing dragon. i WISH i had the presence of mind to have begged or
bribed a ride in the engine!!! one night i stayed in a hotel near a train
yard and it was wonderful to hear a steam engine starting up with a heavy
load ("CHUFF CHUFF CHUFF") then the drive wheels breaking loose
("chuffchuffchuffchuffchuff") and the engineer cutting the power and
starting up again ("CHUFF CHUFF CHUFF") was wonderful. like time travel.

b.w.

well, it looks old and pitted with rust, so it looks like an OLD tool. i
can't tell if the ends of the wires have barbs on 'em. how about scraping
the built up crud off the tubes in a steam engine heat exchanger? (i
don't even know if the tubes in steam engine heat exchangers get cruddy,
just a wild guess.) maybe you can screw on extensions to make it longer
for engines like the "BIG BOY". :-)

Five of the six have been identified:



472. One of a pair of magnetic parallels

473. The end of a fluorescent light

474. No correct answers yet, closest guess so far is pipe reamer

475. Boring tool for a barrel

476. Can opener, this one works differently than most, with the small
forked piece going on top of the rim and the blade cutting up from the
side

477. Flax tool
