What router profile is this...

[sams93]

I am looking for the name of the bit which will cut this 'roundover and a bit more' for an upcoming project.
I think that it is an 'edge beading' bit i'm after

maybe this - Router Bits UK | Whiteside Edge Beading Router Bits
or this - Router Bits UK | Whiteside Machine Co. 10-382 Blanket Chest Beading Router Bit (which looks like it will give a slight chamfer as well)

Sorry the photos are not very good quality.

Looks like you've correctly identified the thing you need.

It does appear to be from an edge beading cutter. There are those that will give you a bead, with a groove ( quirk) to the side that has a square shoulder, and there are those that round this corner off - a detail often found on multiple bead cutters.

If it has been commercially manufactured then finding an exact match is not always easy as they will have run it through a large spindle moulder with there profile but maybe this is close from Wealdons, they do both a large and smaller profile

Thanks for these.

Found this one as well which gives a chamfer to the internal edge after the bead, it's only available in slightly larger size but that might be the one I want.

I'm not sure how much of this profile you will want. A shortcoming I've found is that, in trying to copy old edge bead mouldings, router cutters made of tungsten carbide have a weakness. Because the material is very brittle, it's difficult to design a cutter profile with a sharply pointed 'quirk' to it (which would quickly snap off in use) so router cutters often leave a flat-bottomed/shallow-angled quirk (as mentioned above) which is not a good match (pun intended) for the original.

Two alternatives (for a small/medium-size quantity):
1) Make, or buy, a scratch-stock (or just the cutter) e.g. Lee Valley Cast Scratch Stock
2) Buy an old-school wooden edge-bead moulding plane like these modern copies Side Bead Planes – Red Rose Reproductions

I probably only want to run about 5 metres of oak through it, I will have a read through those bits you have sent though. Depending on how fiddly a scratch stock is to make I could do that instead.

Thanks

If it's any help I used the smallest radius of this Euro cutter to machine up maybe 30m of appliqued beading to an oak faced kitchen I made a while back - am sure you can find something similar for a router

That profile's good but has a socking great big quirk. Something like this would be easier perhaps (assuming you don't want to just make one from the back on an old saw blade, that is):
