Hi Guys,
I was looking at an ebay listing and came across this one: https://www.ebay.com/itm/297518397386

At first glance, it looks like the newest Anniversary loco but on closer inspection, the chassis has been swapped on the engine. I did reach out to the seller for a clarification and he is looking in to it.  ANyway, would the old chassis actually work with the new electronics?

Is the valve gear why you say it does not have the original chassis?

The box says it has a p-n-p board, and looking at the tender it has very nice small rivet heads. That makes it a new gen-7 version, with Pittman motor, brass gears, etc. 
It is still available in the B'mann store for $1,200. Street price seems to be $600.

Why do you think the chassis has been swapped?

Greg Elmassian

Yep, agree, that is the latest, 7th gen tender for sure.

Without detailed pictures of the undersides, can neither confirm or deny the loco.

Hi Mark, The entire loco may have been put in a different box. All version 7 Chassis have Walshearts Valve gear.  The 1225 Christmas loco was decorated the same way in all versions of it. It would be easy for a cheater to put the older locomotive in the version 7 box.  I personally do not believe it is a version 7. We would need pictures of the back head and the underside as well as of the interior of the tender to be really sure.

Take care,

Bill

Bill, you do agree that the tender is the new, v7 design though, right?

I think that this has had its' chassis swapped for an older generation chassis.
The valve gear is different from what is shown in the photo shown on the Bachmann website.
Also, its hard tell, but the front pilot looks like the old design.
Finally, the model number shown on the pictured box,91805, corresponds to the description on the Bachmann website as well.
Just my 2 cents here, but I think that this one is a cheat.
Perhaps not intentionally by the seller...
But it does appear that someone changed that Version #7 chassis for a version #5.

Yeah, as Bill noted, we have a version 7 tender, and NOT a version 7 chassis/rod and valve gear.

The mystery deepens. I flipped the pic on the B'mann store and put them one on top of the other.

Note the airpump is missing on the eBay version.  Could this be a gen-5 Anniversary version with a new tender? We need more photos.

Greg Elmassian

Good theory, why would someone sell the new tender... answer: existing loco with electronics in the old tender, but needed the nice valve gear and the newer drivetrain?

The top photo is the starboard side of the engine... no air pump.
The bottom photo is actually the port side of the engine, and it shows the air pump where it belongs; the bottom photo is a reverse image.

Pete, you flipped the image to fake the other side of the loco, and then say the air pump is missing?

Air pumps on both sides of the loco?

good catch V12 !!

It is pretty useless without additional photos to trust anything about this locomotive and tender. I do not trust anything about this ebay offer.  No further comment on my part until I see detailed photos including the bottom, backhead and the inside of the tender.  I have a personal policy of never buying motive power on ebay because of things like this. it has been fun tho!

Oops.

It did occur to me that a gen-7 tender with all the electronics might be worth a pretty penny.

Loco Bill Canelos

Pete, sure would. If the tender is Gen 7 the the new style plug ins on it would not be compatible with the connectors on the loco if it were an older loco, Right?
