Hi! I have a Model 01 with a few very sticky switches that alcohol can’t fix, and 2 dead switches (broken contacts).
I am not comfortable enough with soldering to be willing to replace them myself, but I also have a Model 100 for work and can therefore part with the Model 01 for some time 
I’m in Austria and have family in Germany. I someone near me would be willing to replace the switches for me, I’ll gladly pay shipping, material costs and an appreciation fee on top
