New 3 gang light switch wiring

[MickMasters]

Struggling to rewire a 3 gang light switch.Existing one has a mix of red/black/green (earth) x 2 and a blue/yellow/red/green (earth) x 1. All switch a light however the last one above also has a separate switch for 2 way operation (the middle wired one)

Can't work out how the old switch wiring relates to the new one. There don't appear to be any markings/letters on the old switch plate to identify the old wiring connections (eg L1 Com etc)

Any help appreciated

Thanks

Can't work out how the old switch wiring relates to the new one.

Similar layout, the three switches are separated as below, and connected the same way, if that makes sense,

Thank you got it and all working fine including the 2 way. It was that old 3 core plus earth that got me struggling.

Well done for taking pictures before removing wires

People are often told to take pictures, but rarely told to first mark wires of the same colour with distinguishing features, like paint spots or tape.

I bet that on the other side it has C B B A to identify which terminals are for which switch.

I can't make out what's under the gunge above the B, but as the other terminals are labelled '1 WAY' and '2 WAY' I'd be surprised if it didn't say 'COM', and that on the other side of the switch there are corresponding 'COM's, '1 WAY', and '2 WAY'.

Most modern 3-gang switches are labeled COM, L1, and L2 for each gang.

Gang 1 & 2 (Single Way - Red/Black)
Red Wire: Goes into COM. (If there is a "bridge" wire linking the COMs together, ensure that stays in place).
Black Wire: Goes into L1.
L2: Remains empty.
It is right?
