Very few of the parts that typically get lost or broken that can't be made from scratch fairly easily, one of the things I love about their machines.
If you can get someone who has the part you want on their own saw, then if they are prepared to take some photos and dimensions you just need to find a local engineering company or fabricator.
What it might cost is another matter.
If you look at the blade guard in the image for example, a piece of cake for a sheet metal fabricator to make. In fact you could probably make it yourself with fairly basic tools.
Always worth a look on French e bay, various bits and pieces do come up from time to time.
