I would like to thank everyone for their suggestions,and will inquire on all of them, and will keep you all posted.
Thanks again
The GN O-8 was pretty much the biggest Mikado ever. Definitely no spokes in the lead truck wheels.
The Tenshodo O-8 had a 48:1 gear reduction, so it should be a good low speed puller.

As others have suggested, it will probably be hard to find exactly the right parts, so a bit of resourcefulness may be in order. If you have access to a train show, you might find a basket-case model cheap. For the trailing truck, the Rivarossi (AHM) Mikado, Pacific, and 2-10-2 used a Delta truck that looked about right. Also, the Mantua/Tyco Pacific and Mikado had one that might be adapted. The Penn Line/Bowser Atlantic, Pacific, and Mikado used a PRR Kiessel truck that wouldn't be quite right, but might do in a pinch. A used inside bearing lead truck would probably be easier to find, or might not be too hard to fabricate yourself.

Thanks for all the suggestions, everyone.
Ed,
Don't know if the lead truck ran spoked or solid wheels, but PSC has 31546 in brass with 36" spoked wheels (they're also available in plastic.) A wheelset with solid wheels should be a fairly easy conversion if needed.
PSC offers Delta trailing trucks in both solid (31556) and roller bearings (31557).
Walthers shows them all as not in stock or special order (prefix is 585- ), but that's almost the $30 minimum by list price.

Finding original parts for these will be close to impossible. I recommend finding replacements.
The GN O-8 2-8-2's had Delta trailing trucks. They had, at times, plain bearing and roller bearing type axle boxes. I suspect they started with the former and went to the latter. A number of suppliers have these. I would look for something with a long tongue and then drill a hole in the right spot.
The lead truck had a 36" wheel. There's lots of those types of trucks available. You could even make your own.
Springing either of these downwards is, in my opinion, not necessary. I've run both front and rear without springs, and they've worked fine. If installed properly.
Hi, Calvin
At one time this outfit carried a pretty good supply of brass repair parts.

Perhaps you could contact them to see if they can be of any help?
Good Luck, Ed
Cal-Scale (Bowser) offers a brass kit for the trailing truck seen under this locomotive:

You might try PSC. I didn't see anything specifically for your GN loco, but they do have a selection worth looking over. Check pages 170-177. If you can find pics of your engine with trucks, either model or prototype, that will give some guidance.

Walthers and some hobby shops stock PSC. There's a $30 minimum order, etc, etc, so ordering elsewhere may be more cost effective than direct.
PSC has a separate catalog for the former PIA detail parts. I think PIA made some parts that PFM's builders used, but worth checking pages 17-19 in it:

Do any of my fellow Model railroaders know where I can get a two wheel pilot truck for this steam engine Tenshodo GN 282, and i need both pilot, and trailing truck on steam engine. I aquired this steam engine at a White Elephant sale, can someone put me in the right direction.
thanks, calvin
