I have an S2 2005 in the UK and it appears to have a similar fob.

Bestidea s.r.l. is an Italian alarm vendor which also made bike alarms. Bad news is they went bust some time back.

Better news is that they appear to have been absorbed by PatrolLine Group as per the link from Roger.

I also found this on google if it helps. http://www.alarmprofi.de/search?sSearch=hpa+937

Everyone loves a Morgan. Even me, unless it's broken again.
