The below picture holds 2 different fonts
I found one which is the Roman script but someone help me identify the one which is used for the W, V and B ?

That is an old stone Wilko and that version of that typeface may never have been digitized. All digital variations that are around are based on Bob McGrath's version for Letraset, are without these W, V and B forms.
With some luck Claude may see this post later and hopefully has an answer on the history of this type.

You can of course add these forms to an existing Roman Script variation

The stone has been last updated in 2004 and I am not sure if the font is a make up or something existing
I thought for a moment that they are Hadfield but they aren't
