Got yet another one for my Forum friends. I am trying to find the right detail part for modeling a NP GP7 passenger hood unit. I have found a bell that's close but it doesn't have a roller bearing sitting on top of the piston. Otherwise, I am completely stumped. As usual, any assistance that can be provided would be most welcomed.

Roller bearing on top of the piston?
Somehow I'm not seeing that detail.
The Gollmar bell ringer pretty much remained unchanged since inception and it looks like the Wiseman bell has a good rendition of it.

I'm under the impression that NP saved a few bucks by recycling former steam bells for use on their GP 7, 9 and 18s.
Cal Scale (Bowser) has several external air-ringer type bells. I've seen some on N-P geeps that seem to have been converted to internal Graham White type ringers.

I didn't either, but that's what the information I was given. Did you take a look at the bell I provided the link for?

I don't know that on the 18s, but I do know that is true for the 7s and the 9s.

Were you thinking the 285?
Hi,
Yes, I did look at the Ebay, Wiseman one and that looks good but, even with the penny, it is tough to exactly get the size of it. Wiseman specializes in narrow gauge stuff so it might be a little small?
The 285 looks good and I really can't see much difference in the 317. They both have the rope pull, and you can see the rope connected to the bell in the photo of the 234. I may have examples of both in my "treasure-trove" of parts. I'll check later and see.
The rope was a backup in case the air ringer got iced up or stuck in dead-center. Many were converted to the Graham-White internal ringer which became the standard on EMDs, two different models.

The 374 in this photo shows the pipe going in to the top of the stem. This bell has been converted to an internal ringer. Fewer moving parts, less chance of icing up, lower maintenance.

The Wiseman is probably what I will get as it is close and the cost is quite reasonable. The 285 I found is rather expensive.

That and I find Bowser shipping to be a tad high for small items, not so bad if you are getting a big order.
I found some #328 with the anti-rotation bar across the top. NYC used some of these.
That Wiseman one should do the trick. It looks like a very clean lost-wax casting.
