...+2 to the above two posts. Capella lugs are pretty easy to distinguish, once you've seen them,
and were only used for a brief period in the Raleigh bikes with 531 frames. if you do a Google
search using that as you term, you'll probably get the years they were in use.

Also +1 on the drops to rule out Super Course.

Here's what a competition with Capella lugs looks like in original paint.



International should have slacker angles, but it is very difficult to judge the difference without a side by side, in person comparison.



As you can see from these photos, the Comp looks like it's the more relaxed of the two here, which are from different years.





Price, especially on a repaint, varies from place to place and seasonally, and Comps go here in NorCal in the original
paint for $350-$500. In any event.it ought to be a nice riding bike, in that Reynolds 531 class of ride feel.


finally, and with some sadness, +1 on the quality of the repaint. Lotsa work required to remedy that.
