Congratulations Pete. Interesting machine, it has design details I know from my 1961 and my 1964 model. Chances are that your machine is from before 1964. I would love to see some pictures when the machine has arrived!

Some folks seem convinced if there is a "1" key-top, the machines type-script must be special. 

That can be an indicator, but it is not necessary true. In the case of the Tippa it is easy: look at the ribbon color switch. The cursive models lack the red option.

One more thing. My Tippa's from 1964 and later are equipled with a Y-shaped part on top of the spring motor. It is an important part that releases or engages the escapement. Usually there is a thick layer of dark grease between the spring motor and the part. I am not 100% sure, but I suspect it is a special kind of grease. All my Tippa's developed problems after I removed the grease from the spring motor. Applying regular bearing grease did not help. Eventually I fixed the issue by adding bearing grease and a small piece of cloth, see the picture in the gallery on the TWDB.

New typewriter day in our home.

The Triumph Tippa just needed a good cleaning inside & out and a new B/R ribbon.

Type alignment is perfect as-is once the ribbon was threaded correctly through the ribbon vibrator.

There were even NO type-key that were sticky through the segment.

Even though the front body panel and the ribbon cover are plastic this is a solid and well-typing little machine.  Right up there with my 1965 Olympia SF.

Case lid is plastic, too, but have survived the years almost perfectly.  Just only 2 nicks in the plastic across the top surface.

That is a terrific looking machine. Does it have the Y shaped part on top of the spring motor?
