              Im not too sure , im guessing a reasonable age judging from the look of it, the frame is away being modified so ill check when it comes back , hoping to have the piping and boilers back from sonic cleaning early next week so will update when I start to rebuild.

                I learn so much from watching you guys doing these restorations. Keep coming with these nice photos.

                  Update , got the boilers and pipework back from cleaning today so started putting it back together.

                  Nice clean frame.


                  Freshly cleaned and descaled boilers


                  Boilers bolted in on modified mountiing points to give slightly more cup height.


                  Getting there , new terminal blocks.
                  Just waiting on group manifold gaskets then they can go on and be plumbed.



                  Thermostats , valves , steam taps , switches ect. are all new. Only reusing solenoid valves as they are still good condition.


                  Hot Water outlet has been relocated between groups 2 & 3 as the customer didn't like it so close to the R/H wand.

                    Lovely detailed work. Are you planning on fitting a PID or keeping the thermostat?

                      correct me if I'm wrong but PID for all boilers and line pressure to the groups for manual soft infusion?

                        Its all staying as it was , so just traditional thermostat. The customer had a limited budget so we had to keep it to a minimum.
                        However to make it look basically new everything external , ie. switches , taps , manometer ect is new.

                          Not on a Linea , The Strada has this as it requires individual boilers for each group.

                            Fair enough. As long as the probe is squeaky clean and you can set it accurately, they work really well. I saw a great thing the other week, which was to replace the DPST rocker switch with two separate single pole rocker switches (in the same housing) to independently switch the pump and solenoid. Simple, but a very effective Linea mod. Or, any other semi-auto solenoid group machine for that matter.

                              Thermostat is brand new with lots of heat transfer paste and the housing is clean as a whistle.

                              That mod would be great on a single group machine but multiple groups could get difficult to manage and make it a pointless exercise.
