No no no not a mamod .
You could try David Auld or maybe even Cranko
Are you kidding?
Look them up and let me know what you think
David Aulds are built tough
Silver solder boilers etc .
Cranko are a bit more rare and soft soldered .
Yes they may be New Zealand made but they are available if you are serious
Roller is restored Cranko
Small verticals are David Auld
