Mend Vaillant VCW GB 242 EH Vcw Gb Eh Boiler

Does the VAILLANT - VCW GB 242 EH Boiler always have an expension vessel ?

I have seen I need to drain down the system prior to pressurizing the Expansion vessel and had it drained today to swap out an old leaky TRV. I looked for the EV but could not find one anywhere, is it possible these is no EV on my system?
