Initial condition assessment
This 70 year old standard typewriter is in reasonable condition, but will require a full clean/oil/adjust as well as the following repairs:
- left shift key broken off and key lever bent
- blow out old desiccated foam
- 5-6 sticky keys; remainder are slower than they ought to be
- broken paper support (surprise!)
- de-rust some of the internals
- replace ribbon and poorly matched spools
- recover platen
- carriage grinding on return
- new feet (old, hard, chipping)
- replace foam with new felt
- the aligning scales for the Perspex card holders aren’t functioning properly (broken or missing a spring?)
- polish keys and spacebar
- brights all need attention and polishing
Repairs on 2026-02-02
With some of the quick repairs listed below, I’ve got this machine up to the level of pretty good acceptable daily use condition. It’ll definitely be a serious member of the rotation once the C/O/A is finished. If it had a more standard typeface it might have a shot at replacing my elite Royal KMG.
- basic wipe down of dirt, dust, etc.
- fixed carriage grinding on return
- replaced spools and ribbon with nylon blue/green
- blew out old foam as well as other internal dust and cobwebs
- basic cleanout of segment to get keys unstuck and working well enough
- basic oiling of carriage rails and one or two additional spots

Olympia SG1 Typewriter Manual
My machine didn’t come with a manual—standard typewriters without protective cases rarely ever do. If you happen to need one for yours, Richard Polt has one in his collection: Olympia SG1 Super De Luxe Operating Instructions
General Comments
As someone who uses a lot of index cards, this seems a spectacular machine. My one immediate issue is that I wish the paper injector went down a few more notches as I have to roll it back up a few lines to get to an acceptable starting line on my index card.
