Help identifying this BP/W

[nick73]

I am confused about a bp/w configuration that I am offered at a very good price, and I would appreciate any help: To my understanding the traveller pro comes together with a nylon blackplate and an integrated tank adapter. I attach some photos, showing what looks like a traveller pro wing, but with a metal backplate and a detachable single tank adapter (with the weight insert). So, what do you think?

Wing identified as "Traveller Pro 40"



But has a metal backplate and a tank adapter?

It looks like the traveller wing is just combined with a SS backplate, pad and a weighted STA. As the gear is modular its not uncommon to piece things together. As it is, that's a very good cold water dive system, I hope its not for warm water.

But I thought that the traveller(pro) is not modular and comes with a fixed configuration (as discussed also here https://www.scubaboard.com/community/threads/traveler-vs-eclipse-infinity-series.489852) ?
OTOH, it will be used in the eastern Mediterranean, usually 18-25 C (64-77 F). What would be the problem?
