Does anyone have advice on how to add a knuckle coupler to the HP E-7?

My BIGGEST improvement would be to get them out of the closet and onto the workbench...!!!

Are you referring to the later version with the improved truck sides and detail, or are you simply wanting any modified HP E-7?

I have an early version one but wanna see any of them. I got it recently and wondering what to do with it. it has a new motor running really smooth after cleaning and lubricating and shity blue paint so i have to make a decision just to paint it and leave on the shell or totally rebuild it trying to make a model. Just want to know points and possibilities to work with (and steal your ideas)))

Well... here is a drawing of what the HP E7 shell SHOULD look like;

The biggest missing element is all of the panel lines...

On the prototype, these are flat strips with rivets through them... but in TT, we could probably 'suggest' them with plain resin panel lines. (e.g. https://www.archertransfers.com/AR88013.html)

Back in the day when assembled model planes I would use a height gauge with the scriber and a universal right angle plate on a granite surface plate to scribe panel lines.

Hi Murad!
Here are a few pics that may help. These show teh biggest differences, the trucks and the nose. Both of these have the cast nose that is soldered to the brass body sheet, but there are a few differences. You can see on the unpainted one it has number boards and a second headlight compared to the earlier painted one. And if you look at the front pilot you can see it's slightly different on the older versus the newer, the angle is a little different.
The painted one is missing the radiator panels on the roof, but I have seen them on other older ones so I think they were available on all models.
The trucks are the biggest difference, you can see the older style truck uses the stamped side frames and they actually hold the axles in the truck. The newer truck is a one piece, similar to the Kemtron diesel truck and the sideframes mount differently, so you can't interchange them.
I couldn't find my others to compare, There is an older version that used stamped metal for the nose but they're a little more angled or pointy where the front of the nose comes together. I think they are probably the rarest, they must have been hard to assemble compared to soldering the cast noses on. I'll see if I can find the others and post a few more pics.

Started the restoration of my early E7A today. First, checked the gears and lubricated it well. Then cleared all electrical pickups and made it runnig pretty well. Right now have to clean all the old painting and fix some cracks on the front casting. Is it solderable?

Don't they have N scale rivet strips that'd be better than the plain panel lines?
