hello

[Idris]

As I have no clue what so ever to the value of these, I would appreciate any advice given.

Although I'm no expert on the Yesteryear range, you appear to have a number of non-standard models, including what might be hand-assembled prototypes. If proven to be genuine, each one is worth a significant sum. I would therefore strongly advise you not to rashly enter into any deals until such time as a consensus regarding originality has been reached.
Just out of interest, whereabouts in the country are you? (It may be that we have a MoY specialist in the area who would be prepared to inspect the models in person.)

[Idris]

Any chance of close-ups of the 1-75s, please? (Looking at your group photographs, I think you have just two - a small red double-decker bus, and a larger silver/white bus with superfast wheels.)

Here you go.

Thank you.
I don't think either of those is particularly exciting, although the red bus appears to be the first issue with the green/yellow decal. As such, it may command a slight premium, but the chipped condition will bring the price back down again.
