Hi there - from another one from Germany.
Since the day before yesterday I also own an Raleigh Rialto. Serial Number: GE01...
So Netherlands, April - and I think 1980 should match.
Some pictures:
And a large one (1.4 MB) - therefore as link:

I changed/repaired nothing so far, the pictures have been taken on the day I went to fetch it.
The previous owner told me he left the bicycle for 20 years locked up, now he sold it at eBay.
I have noticed a few differences from the orange Rialto in the first posting, maybe someone can tell me if my Rialto is from 1980 - or is there a rare possibility that it is from 1970?
Greetings, Martin
