Jon,
Ok, bear with me....as far as a built line or layout, yes he did. I think. He was very connected to the logging industry in Northern California. That's where he and my Mother are from. Back then, if you lived in Northern California you either worked for the RR, cut the trees down, worked at the mill or on the water for the mill. My relatives all earned their livings in the industry. 4 of my cousins still do. So, that being said, he had a large space around his Koi pond that was his logging town. He has tunnels, buildings, bridges, water towers, fake trees, lights and so on. He loved Shays!! He had 4. However, I've kept one, as well as 2 of my sister's and a new one we sold. He had a brand new LGB Mallet engine, along with a LGB Unitah(?) (I know that's not right, but close maybe.) that I just sold, and we still have 1 new and one used Bachman Spectrum Baldwin something or other engines, another New LGB 2010D Engine, as well as the LGB2020 Set. There's a Bachman Engine that's old fashioned-ish that's green and has writing on it. Southern something? There's also a really neat Rail bus? This one has not one marking I can find as to who made it. I've looked tirelessly trying to find out what it is with no luck. This engine has 8 windows where as I'm only finding engines with 4. I'm sure you know. There's another Bachmann engine that's kinda ugly so we're giving it to some of the grand kids. LOL! That leaves 4 unopened Bachmann flat cars with logs, 3 unopened Bachman Tankers (Mobile and 2 Conoco), 5 LGB tipping Ore Cars, unused, but.....he painted the coal gold. I know, why???? I still laugh about the hard time I gave him when he did it. There's 2 Bachmann flat cars and one with real low sides. Baldo? It's yellow. There's 4 or 5 cabooses, LGB, Bachmann and an Aristocraft. There's also a little LGB wine barrel car. He had the Napa Valley set. That was the first thing we sold when I saw how much it upset him. So none after that. Then there's the Pola buildings. Lots of them. A sawmill, coal yard, observation tower, water tanks, houses, stores, train depots, big double doored train garages type things, bridges, and so on.
He also had all of the sets of the Bachmann Big Haulers. I have the Pennsylvania, he gave the others away to any kid who's eyes lit up when they saw his trains. There are people, parts, track ( some new), the power deals that make the trains move. So, so much. Most all of the rolling stock is in original boxes. Except the Green engine and the rail bus. The buildings are built, no original boxes. The new LGB track is in original boxes. I'm not sure about the cabooses. The trains are at my Parents, about 13 miles from me. I will get you some pictures asap. I've sold quite a bit on E Bay. I was using my son's account, but that was too difficult. So, I opened my own account that has a 5 listing limit per month. I wasn't very pleased with that, but I guess that's the rule until you prove you're responsible as a seller.
There's my life story. LOL! I'm a yapper!! Feel free to ask me anything. I may not have an answer yet, but I will, eventually, with some help.
