My friends SSN in Rotterdam restored this original WD Austerity, a 1943 Hudswell Clarke. It is now a runner as NS 8811 , but the gauge glasses on it are industrial ones and they don't work right and are difficult to read. As their 'correspondent' in the UK I'm being asked if I can find some original Austerity gauge glasses for them. Does anyone on the forum have a pair, or know where to look? Many thanks for your help.
