Hi to all and anyone who may be able to help...
I have a Zacconi Riviera Baby Lusso and need a new boiler pressure cap with release valve built in as the plastic/Bakelite is badly cracked.
I also need a new chrome grill as it's missing from mine...
Any guidance info or direction would be most appreciated...
Regard, Paul
