These engines, after much deliberation, have been confirmed as Schoenner 112/21 and 112/22, circa 1900. Thanks to Oliv, Maxwell and others.
I had some time to work on the boiler of the /21 today. One of my slipshod solder jobs on the SV bung had failed, so for good measure I re-soldered each of them while I had the cap off. Shortly the boiler was ready for the bath:

After 25 minutes, the color was looking appropriate:

So I carried on with reassembly.

Doing a great job so far Benny - it's coming along nicely! Following your thread is giving me a lot of ideas on how to go about a restoration like this - thanks for sharing.
Thanks, Larry. It is part time research and part time restore. I feel like I spend as much time reading as I do actually working. The engine base paint had me befuddled, with the nice green wash over the brown....turns out it's as easy as that- a wash. Thin highlight paint with water, then paint over your base color. Test pieces have produced good results.
Thanks for the feedback and I'm glad I can be helpful.

Really like the DARK red used on the flywheels, as it has an oldish "feel" to it!
The mounted wheel is original paint. So, I had an original color sample. Jut some trial and error with the colors I had here. Oddly enough, Harley Davidson Deep Candy Red with a touch of brown and a small amount of thinner shot the closest color. I didn't prime, as they didn't seem to do it from what I can tell. Just fill up the airbrush and ran about 10 light coats, then clear lacquer.
The toughest part is getting the color right but hey you can always clean and respray if you mess it up.

Lookin Good 8)
Thanks, Nick. Hopefully I can get it painted tonight and perhaps work on the blueing solution recipe. I still cannot get an even color across the entirety. I got a magnetic hot plate stirrer now so we are going to try it properly mixed. Plus, it isn't 50 degrees in the shop so getting the correct temp hopefully will be easier

Progress update on /1.
Firehouse and boiler nails were gently straightened and removed. Engine was unsoldered and removed, exposing the base. It took a bit of scrubbing to remove the remnants of what appeared to be the pork fat they used for combustion.
[attachimg=2][attachimg=3]
Boiler, housing, engine, flywheel and chimney painted with something that absolutely refused to let go. I spent 4 hours gently, then vigorously, then outright frantically trying to remove this god-awful substance without doing damage. [attachimg=4][attachimg=5]
The engine and pillow blocks were stripped of the gold paint, and nickel was polished. The cylinder cover blueing was near perfect. Makes you wonder why someone would paint it. I've matched my colors(I think) and next step is respray base color and apply top color wash. I went ahead and repainted and polished the flywheel- I think the color match was pretty good.

You won the auction over my brother but I am happy to see that the engine is getting fixed up!
Great work. What is the name of the cold steel bluer?
I thought about bidding too, but after a recent re-orgnization in the steam room, I decided it would probably remain a project for many years to come! :D
Glad you got it Benny and can't wait to see more work done to it. I also am very interested in getting that correct purple-blue color...
-
I think it is Birchwood? Super-Blue. Readily available anywhere shooting supplies are sold.
Danny has mentioned a brown patina is available from them as well, but I've never seen it.
Tell your brother I apologise...Maybe next time. He may be happy, as it still requires a good deal of work before it will steam, not just soldering all the bushes back in place....not to mention the missing safety valve. That's an easy 25 bucks if I'm lucky for the correct one. And finding one without having to but the engine so far has been challenging

So, one started...hopefully can figure out the recipe for the blue before I go mad. The other could prove just as bad. The boiler is brushed with black paint along with everything else. Hopefully I can carefully remove this and find some nice pristine finish underneath.
On a good note, the 1689/0 came with this little grindstone...[attachimg=2][attachimg=3]

The boiler has lost some blue over the years and has loose bushings, and a loose steam line to still be repaired. I just wasn't happy with the effect commercial blueing solution was having on my test pieces. It never quite got the violet-blue I was looking for; always more black than blue. So after doing some research, I have added a laboratory to my insane little workshop. Color tests are still in progress with donor boiler. Care must be taken, as almost all these compounds have some really nasty warning labels. And I'm pretty sure I have some sort of list when I placed the order...[attachimg=2][attachimg=3]

I've touched up the blue on the steel parts, given the wood a good cleaning and oiling, and spent quite some time removing gunk and rust from the lithographs tin base.
I used commercially available cold blue solution to blue the steel, and it did not achieve the same greenish blue as the remainder by the appearance is much better.[attachimg=2]
The engine base, while dirty, have every bit of the original smoke effect paint. Quite fetching.[attachimg=3]
-
On both, the blueing has, as usual, burned away from the firebox and chimney and rust has moved in. [attachimg=2]
The bases, as nuvolari has pointed out, are glued together and the old glue has weakened on both. A good scraping and a bit of fresh wood glue and some clamping are in order.[attachimg=3]
-
Both are in equally rough condition...[attachimg=2][attachimg=3]
I am not so keen on the gold and black paint. I can only hope there is something original left beneath it.
-
I recieved the first a few months ago, and set aside for later. In the meantime, another appeared on eBay. I managed to win the auction so on the way was the second...
Very little info I can find on these. Schiffman's has rudimentary specs, and the measurements jive, but I will leave it to the wiser members to help determine if I'm correct.
