Hello, you have a very nice lot of DG stuff, indeed! I have a Nova 3 sitting on the garage, waiting for proper repair. However it's missing all the front panel switch levers, so I would need to rebuild them, not having had the luck of finding some at reasonable price. I have some picture of the original Nova 3 levers, however I didn't manged to have the exact size to fit an obtained plastic model very well.
Would you mind to take one cover apart, and put it on a flat-bed scanner together with a clear ruler (in the same picture), so I can measure from the image the exact sizes? The profile is not the same, but I can obtain it from the camera pictures I already have, using your images as size reference for rescaling. Thanks Andrea
