Recent Ives 1134 purchase, video added

I just purchased the 1134 shown below from Cabin Fever Auctions.   I have bought a couple of items from them recently and they have been great on answering questions and shipping promptly.

I don't own much standard gauge (should I say wide gauge), but this has always been one of my favorite engines and wanted an older looking one rather than a new MTH.  It was really filthy covered in dirt and saw dust, so I took it apart and cleaned it, documenting the dissembled parts.  I was looking for some folks with expertise on the originality (or repo parts present) and help determine is this a typical example of this engine because of zinc rot with the repo parts ( or maybe more of mutt where it has parts from several different runs of engines) .  There is very limited information out there online.  Also looking for rough estimate what its worth.

I was impressed with the parts used on this engine assuming it was from 20's, as there are bearings on the two drive axles, also rotating gears and also on both sides of the motor.  Some of the bearings are even stamped with Ives copyright.  I did spend some time removing the old oil from the motor bearings as it had become solid over time and locked up.  The drive rods are really odd, as they almost seem like they are made out of lead as they are super soft and bendable, is this normal?  The motor fired right up and e-unit worked great (very surprised by this).  There were allot of screws in what seem like difficult position to remove, wondering if there is known or preferred method for disassembly.

Some of the examples I have seen of this engine has some sort or lever coming out of the cab for the reversing unit and mine does not.  What does this lever do and should mine have that?

I am needing a new pick-up roller for it, who could I get than from?

I think the following part are reproductions but not sure.  Any feedback would be appreciated.

-Rear Trailing Truck looks new

-Drive wheels look new

-Rear aprons look new

-Not sure about the tender/tender chassis/wheels/coal load

-Pilot looks potentially newer and smoother that the boiler

-The headlight holding device I was suspect of missing pieces, I end up using shrink wrap to isolate it from the grounded mounts.

Thanks!
