Can you help to identify these frames, bikes or parts?

Does anybody know what Brooks saddle this is?

Has B-74 engraved into it, am I right in thinking thats the year it was made. Also has a couple of 'Made in England's dotted around the place... no idea what it is though...

No, 74 is not year of manufacture. I'd guess it was a Brooks B74. They still produce B72 and B73, which are similar to yours.
