Edit: just looking at that photo, do I need to think about whether the seat stay is vented? That seat stay will have a brazed on cap right? If the frame I'm trying to fix is the same, is there much chance I melt that braze or would it have been done with higher temp stuff?

If you're just brazing the seat stay onto the side of the seatpost lug then venting isn't an issue. The seat stay may have a brazed on cap, or it may have a top eye fitted - a big cast braze-on fitted to the end of the seatstay like one of these:

If it's a top eye then you should be fine with brass. If it's a thin plate brazed on the end of the seat stay then I'd suggest using silver rather than brass to reattach the seatstay - the lower working temperature will ensure the end plate isn't affected.

Thanks for that.

I'm sure I must have seen these top eyes on the ceeway site before, dunno why I was thinking a plate was the only way to do it.

I figure it'll be the top eye due to the quality of the frame, as it looks a simpler job, the plate way would take more 'fitting' I reckon?

Yes, the plate method is much more labour-intensive. If it's a mass-produced frame then I suspect it'll have top eyes fitted.
