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

Thanks Rik

I am confused too. Maby ill take to it with a wire brush and see if any numbers will come up. Also odd it has only one braze on for a gear shifter.

I've been a little mystified by this one, I must admit. I've never seen a frame with a grease port (common up until the 50's) with a seat clamp (not particularly common until the 90's)... The lugless construction is interesting too and helps narrrow it down.
Claud Butler is a good shout, but I think you also should look at Holdsworth who produced a model known as the LA QUELDA - lugless construction with a seat clamp.
