Ok, got the S1 in today and tore into it.
All I'm all, I'm thrilled with what we got for the price. Original packaging, including all foam and protective inserts.
The shell and chassis appear flawless, no broken bits, no scratches, really nice.
HUGE bonus, it appears that ALL of the exterior detail parts were included in a separate bag. All the pop valves, ladders, handrails, lights, panel covers, running boards, headlamp assemblies... It's all here. This is honestly the biggest surprise because the auction ad says "no parts / motor"
Upon removing the shells from the loco and tender, the gearbox covers are both present, as well as the motor mount (big plus here!). So I can work with this. The worm gears are present on the drive axles. All wheel assembly and piston rod assemblies are complete.
Now, definitely going to need the driveline including the worm shafts and drive shafts. I may have a motor that is strong enough, otherwise will be looking to source a motor.
Tender has a 4 ohm speaker installed, but I'm going to be installing a PS1 boards that I already have, so that will get swapped out. Other excellent news is that all wiring harnesses, tethers are included. Even though they're configured for PS2, it's easy enough for me to use them to run PS1 stuff back and forth.
Even had aPS2 smoke unit with all wires and connectors. Unfortunately I can't use it, so if anyone wants to trade me a PS2 smoker for a PS1, let's talk.
Will forward this info to Midge as well, fingers crossed she can help with the drive shafts.
Edit: @Lou1985 & @harmonyards: Do the gearboxes also need a bushing / bearing at each end for the worm shaft to sit in? The gearbox cover plates are present, but I can't find any sort of bushing that has a round hole that can fit in the slots on each side. I'll also ask Midge.
