atari 1040 STF(M) Limited edition

An interesting addition to the collection is this 1040STFM. It's told to be STF but since it has the modulator, it is not. Arrived from Germany in it's original 1040 STF box. There is this blue print Atari ST logo on it (same style as 2080STF Yugoslavian distributor upgrade Ataris) and the Limited Edition sticker on the back. It has 1.04 UK TOS and UK keyboard, however the documentation from Atari is in German. Probably it's from a limited series of distributor/importer series . All in pristine condition.
Feel free to message me if you know the full story.
