We don't want to clog the archives Polybus, as you say, but we do want to record rare and interesting machines. Ten pictures of a modern machine, or even an elderly but common one, would not be a valuable contribution, but the rarer the machine, the more important it is to archive details of it. Provided the machine is fairly complete and the pictures are good ones (as yours are), they are well worth preserving.

Of course, now that we've preserved the pictures, we do need to know the model and serial number - are they on the top face of the crankcase as jonesy suggested?
