Hi
The info that I have regarding the Double Diagonal (only one in existance?) steam engine is that it was attached to a 4 colour printer which Lang B supplied to Bollington Print Co. in Bollington near Macclesfield about 1903, although it could have been used to drive a stenter or a Calender or Beetling m/c.. The one in the Bolton Museum has a 9inch bore and 16 in. stroke but Lang's also built one with a 12in. stroke. They built them with various bore/stroke combinations to suit different requirements (horses power).Lang's also made a single diagonal engine known as a(n) "Angular Engine".A "High Pressure Horizontal Steam Engine" was also manufactured by Lang's in different sizes depending on the number of horses required to drive the m/c. Now mr. Rivetlad, I'm sorry to say, all these engines had cast in nameplates............ but........... they also made an "Inverted High Pressure Steam Engine", specification unknown, which had a name plate screwed onto the main frame, just stating "Lang Bridge Ltd, Makers, Accrington". I don't know how many were produced or what machines they drove but I hope you find one. The only brass nameplate (souvenir) of Lang's I have is a "Lang Bridge Automobile Club" from about 1966/7 up until a year ago it was still wrapped in it's original tissue paper.

Retlaw , it doesnt surprise me that you could'nt find any patterns for this engine in the pattern store even Lang's would have realised that the age of steam was long gone. There may have been patterns for parts that wear or could get damaged/broken, things like cylinder or trunk giudes, but main frames they are too big and their space would have been needed for new patterns. If in the highly unlikely case of the main frame getting broken it would be much quicker and cheaper to replace it with an electric motor. Just my thoughts on the subject.

Best Regards
