I think about that, but they see it
IF it's one of the regular train auction houses. There are enough knowledgeable people looking at their listings to ferret out everything good.
If it's not a regular house and it's poorly listed there MIGHT be a deal. I've missed items that were seen by others and got great deals on rarities no one else saw.
With the stuff I'm into I tend to place a higher premium on some variations than regular collectors. So with those items I try to keep my mouth shut.
Here's something for you Mike:
I wired up the lights and all visible bulbs are vintage and correct. The two on the station are lightly interior frosted and the filaments just glow. Might be from about 1920? The tall street lights are probably from the early '20s.
