Thanks David,
I don't use the little Brodak's so I don't know what they look like! I knew there was a Mk1 (made by CS?). I didn't realise there was an 0.061 Mk1 either. You live and learn. By all accounts the Mk2 Brodack 0.049 is a good engine, so I am glad it isn't on its way out!
Regards,
Andrew.
