I knew the armor train had Russian origin but didn't know about the Japanese connection .

The Fiddlersgreen link I have in my many paper "favourites . Paper has come a long way in the past couple of years and bears watching by all modelers .....price is right and the quality is really getting good . Check out flat front structures at http://www.kingmill.com 

As for tanks , I like the British Mark series


 They're sort of an armor version of a critter , to me . Some of the armored cars are interesting too .

HIYA !!

I found a few great prototypes for traction critters.

http://davesrailpix.com/hicks/htm/hicks396.htm

http://davesrailpix.com/oerm/htm/oerm47.htm ( This one is a rail Grinder)

http://davesrailpix.com/oerm/htm/perris35.htm

This is the link to the whole web page, LOTS of great traction pics here!!

http://davesrailpix.com/

I'm going to contact the place where the first link is and try to get a better picture of the truck.( at least one with out all the grass)
I also found one that had a tiny steeplecab "trailer" behind a PCC car truck.
These would all be called on for light duty, I think the steeplecab could only manage about 6-8 cars if I recall correctly.

Thanks for the links ....I'll save them for future reference . Right now me and 4 other retirees are almost finished building Ebbets Field ( Brooklyn Dodgers ) ballpark in O scale for a customer . It's been 11 months in construction so my interest has been in that direction lately ...haven't forgotten the traction locos , though .

  HIYA....

 

     I found some better photographs of the Singer sewing machine critter and thought I'd share.... I think it is the same as the bleach loco... sure looks the same to me!!

   Using the Ballpark and hand grenade system, you could make a nice model of it with these pictures!!

   It would be very easy to build the truck using the B/W photo, and the whole thing could likely be done over a weekend. I would think the lower costing FLEA from NWSL would be the best for this one as the cab would hide the can motor!! Or if nothing else hide it under the seat if you made it a 1 controler type critter, maybe turn the motorman sideways or something.. And have the controler in the center to hide the can.

Notice that in the B&W shot it has a "flopover" pole?

Sprung in both directions, so that in a confined area you don't have to "walk the pole around" to change direction.

I'm sure that flopover isn't the proper name--just what I call them.

HIYA.....

Herb, to model that flop over would you just double spring it then just make it able to revolve?
How would you keep from having problems with the wiring? Put trolley pole stops on the inside to keep the poles from going more than 180*?
You would have to put some sort of ear on an extended tube attached to the pole or something like that.

Mal Soverel did a series of trolley pole construction published in Craftsman in '48 or '49--I think that that double spring flopover was one of them--I will have to go look. If you are interested enough to try building one--the article describes O scale construction, but HO would only be a little more fiddly ---I will see if I can find it, and Email you a copy--don't want to post it here because of copyright. Your "cost" will be a pix of the finished pole.

Mal sent me copies of some pole and pantograph drawings on the back of correspondence, over the years. Mal was -- to put it kindly--frugal. He would write on the back side of proof sheets from the NMRA Bulletin--which--being only to check before printing were printed on the crappiest newsprint paper which is now falling apart. He would re-use envelopes by turning them inside out. At the time there was a first class postage stamp that was dark blue, and the cancellation didn't show on. One of those sent 6 or 7 letters cross country before it got too smudged up. I participated in that experiment--but I digress. 

Meanwhile--for your edification and enlightenment- here is a print of another style flopover --a US 2A. Mal used a free copy machine that didn't print very dark--so the scan is the best I could do.



and a US6--which is basically a single spring version of the base in question (not a flopover)



Hope that these are readable--I have my doubts.

Your comment about model poles makes me think that you are fastening the motor lead directly to the pole. BAD! Impedes pole movement. Pole should have a pivot pin that turns in a piece of tube, with the motor wire soldered to the tube. Better yet the pole can have a threaded pin, that screws into a tapped socket - keeps the poles from falling out, if the pole is "up" and the car is inverted

  HIYA,

    That is the way I was thinking of doing it, with the tube. 

 But then again, I failed to realize that with the contact tube being there you would not need to worry about how much the pole rotates. I wonder just how small  (short)of a can you can get for a FLEA drive? I'd bet the real one only moved 2 cars max.

 I think I was hoping for or thinking of having a decorated cab for the folks with magnifying glasses out when I show it off!!

 That's me over thinking something again..
