It's a Thornton Pickard shutter fitted the wrong way around not that it'd make any difference, Houghton's may well have put their own Sanderson "Brand name" badges on them. Looks like it was a Front mounted shutter, these have a fixed panel both sides, the Between=Lens shutters (TP's name) usually have an interchangeable lens panel.
It's definitely a German style "Reisekamera". They were still being made in Russia until quite recently by FDK, I'd guess most German production ceased in the late 1920's possibly early 30's as there was a faster move to 35mm and precision 120 film cameras than other countries.
However if German production mirrored the UK a few may have been made up to the early 60's but I've not come across any. The last major UK manufacturer making tailboard cameras, Watson, ceased trading around 1958, although Gandolfi could still make them and they ceased camera production this year.
One thing to remember was that the English style Tailboard cameras were all quite similar, many almost identical, and it was the same with the German Reisekamera's.
