[CR] Headclip headset wanted

Hello CR, long time no write.

I have a 1940s Australian track (road? path racer?) frame made by "Seagull". It needs a headclip-style headset, if I understand right. I have very little knowledge or experience in this regard. The frame has integrated cups for headset bearings, but there's no slot in the fork ( http://www.flickr.com/photos/fnagrom/5429022430/), like I think there might need to be for a headclip-style headset.

Do you have a headset that would work for this frame, that you'd sell me?

The rest of the period-correct parts (Wrights, Airlite, Williams) that I'd want to use are just too rare and expensive to source, so aside from the period headset I'll probably build it with modern parts.

Also, am I seeing right, that this frame is drilled for brakes front and rear?

Thanks,
