The whole machine was filled with grit so a lot of my time was spent just getting the Arizona dust of the carriage guide rails. A couple drops of oil really freed every thing up.
As Ted reported, the platen is in a sad state, but I have never seen an original Hermes platen that wasn't rock-hard. Fortunately the feed rollers are still really soft and grip the paper well. If you use two sheets of paper it works great. I tend to use two sheets of paper regardless. If time and money is freed up I might send the platen to Ames for recovering.
This model has a twin ribbons system. It can use standard fabric ribbons or the lovely high-definition film ribbon. This particular machine came with a completely full film spool so I didn't have to install a ribbon.
As desktop typewriters go, the Ambassador is really ridiculously large. It dwarfs pretty much any desktop typewriter. My HH looks like a portable next to this thing. I have no idea why the size. Maybe it's the one typewriter to rule them all.
No students have used it yet, but I will make it available tomorrow for part two of a two-day project. I am sure there will be some interested takers. It types like a dream and is filled with every bell and whistle. I love the paper injector. It makes you feel like you are shifting a really fast car into first.
The decision that I am facing is whether I should make this into a Silver Surfer. Shining it to a mirror finish might make this the most formidable typewriter ever.
