I’ve just acquired a Century 100 with the engine number LLS 1200 R7.
According to the list of engine codes, the first engine number for the LLS during year 1956-7 was 1200.Could this mean it was the first of this type off the assembly line?
I believe the R means that it was factory reconditioned and the 7 signifies the year this was done,but in which decade?
I’ve also noticed that the carburretor is on the wrong side, (oppposite the tiller) and is an Amal,could these have been fitted as part of the reconditioning work?
First Century 100?

Well it could just mean that. It's worth remembering that Seagull numbering was never an exact science! The seven is more likely to mean 77 than 67 as it would have been a bit too new in 67 for a refurbish, but the 7 applied to either - there was no fixed code for this.
The Amal carb has a larger diameter than the Villiers - if there is no spacer/collar around the inlet stub then it's a Silver Century block. It's unlikely, I reckon, that the factory would have supplied what is effectively an upgrade although anything is possible - around 1977 the company went through some strange times.
The Amal carb together with the Silver Century block - would give a fairly useful increase in power over the ordinary Century - British Seagull claimed an extra 25%, and charged £55.0.0 for a Silver Century instead of £42.10.0 for a Century in the late sixties.
