Wow! Amazing work here - I'd jump for one if/when there's a group buy. Kinda 1924 meets the Durham Dorset. There will be a group buy soon. Watch TOST. (I might add ATG or TSR as well, but I want to keep things simple for me).
I was fortunate enough to acquire a TNNSER 3D, as part of a run organised by Andreas @riverrun. I had a Shave with it yesterday, in terms of performance IMHO up there with the likes of a Streamline/1924 but more forgiving.
