[Nick England]

John Toebes has finished the 3D model and says-
------
The model as it stands is public (

)
and if anyone else wants to take a stab at printing or editing, I’m all
ears.

John is investigating the best way to print, regarding smoothness,
supports, etc.

Michael Katzmann reports on the German eBay ribbons
Note - I think the eBay buy it now price has jumped from $75 to $95 plus
shipping.
-------------------------------------
Michael says
   The NCR ribbons from Germany are perfect.
You can see the comparison between the original (that was in the machine
for 30 years) and the NOS ribbon I just installed. (the new ink is dark
violet).
[yes the photo looks really good - Nick]
Yes, it's pricey ... I paid around $100 (for four) with shipping.
1 item    $55.00
Shipping  $38.28
Tax*      $5.60
Order total  $98.88
(I made an offer and accepted the counter offer of $55 but think the price
has gone up since I purchased them)
