I have a Type 203. No F, no a, just a serial number 0603. I have no bottom label, The information on the bottom is stamped into the bottom. No holes other than for two phillips head screws holding the bottom on. Inside the grinding compartment, the blade is held on with a conically shaped hex nut, plastic. It is a 120v, unit, no doubt for North America.
There is absolutely no information on this specific unit on the web. Krups doesn't even seem to know it exists.
My problem is the blade edges are pretty beat up after almost 30 years, so I would like to either replace, or refile them. The grinding seems to be inconsistent as a result, with many larger grinds and some almost powdery grinds each time. Motor works perfectly.
The blade itself is actually inset into the bottom of the conical hex nut, so turning it while holding the blade will not work, and will result in damage to either the blade, the nut, or both.
