Sealed Headset bearing identification/purchase

I have a condor 1 inch aheadset/ threadless headset (circa 2005) on my bike and the cartridge bearings are starting to give out. They don't have anything written on them, I have checked carefully. Condor don't stock them anymore and don't know what they are. Is there anyway I can find out? I can measure the inside and outside widths but what about the angles?
Are headset bearings the kind of thing regular bearing companies even stock?
Thanks!

If it's a cartridge, it's probably standard, in bicycle terms, and it was probably made by TH (FSA).

There's only 45° or 36°(from the top of my head, I may be forgetting something), it's not hard to spot. Check inside, outside, height and angle and buy the same. Or try to find what headset came with the bike.

Thanks y'all. Condor were basically useless in identifying or helping. (Surprise?) I don't have callipers so with a bit of ruler measurement and angle guessing I think I have found something that will work. I've made an order and we'll see how i get on. Telling if the internal angle is 45 or 36 was much less easy than it sounds but using a bodgy method I think I figured it. Thanks again for the help. Wish me luck!

Cut a square of paper down the diagonal is the easiest - Tester on here approved method!

For the internal, just take the square corner and see if it'll touch the opposing sides.

For the external, put it in a square inner corner and see if the contact points of the taper hit the measuring device the same distance from the apex. For 36 degrees, one distance will be about 3/4 of the other.
