If you want a full 3D model of the plate that I took off my machine along with accurate font rendition, I put a model up on Onshape at https://cad.onshape.com/documents/f53834bacb2e2e61b842dcb8/w/27a9beb6f12715a0c20486e2/e/91bb42615d4820ee414d19e2

To help keep the front panel in place, I used four simple 3D printed mini-brackets. The Model 33 is a testament to Wayne's ability to recover a seemingly destroyed unit..

Photos attached along with the OpenScad model - a simple aluminum bracket would work as well..

Here are a couple of photos showing the lettering..  I can get some more precise measurements if needed.

The front plate is held on by a 180 degree bend on a tab in the middle of the plate.  Also there are two small nubs on the base pan on both sides that keep it from falling out.   

  

It just slides on from the bottom with the middle tab sliding under the plastic cover and the plate slides over the two nubs and clicks into place.   

  

On a 33 the Line/Off/Local switch helps hold the right side some.  On Telex 32's there is nothing to help and the front plate slides off sometimes.   

  

Here are some pics that might help.  The front plate is off a TWX 33 and the labels are homemade.  The hole for the knob is slightly larger than the diameter of the knob.  Its not pretty but will work. 

  

I forgot to take a pic of the 2 little cutouts on the plate that slide over the nubs but you can see one in pic #3. 

  

The pics will probably get bounced on GK but they will show up later.

Does anybody have a detailed engineering drawing for these? 

  

And also information as to the thickness of the material? 

  

And - how is it held in place? 

  

I am in the same position - My ASR33 is missing the front panel. 




Kindest regards,

Hi everyone! I’m in the thick of restoring a pair of ASR-33’s and both are missing their front panel/plate cover decal. Does anyone on here have one (or even two!) to sell/trade? I may have other ASR-33 parts to offer in exchange.  ______________________________________________________________
