Wanted: 15 tooth track cog and BB lockring

I'm looking for a 15 tooth threaded cog and a BB lockring for a 'suicide' (hehe) setup on my university beater. So it's a normal track cog I'm after, but an old-fashioned British bottom bracket lockring rather than your normal LHT track-hub lockring.
This is supposed to be a cheap bike, so I'm not really up for spending much. Used and working condition is fine. I'm in the South so it'll have to be posted. Hope someone has one lying around :)

I've got a BB lockring somewhere... Will dig it out over the weekend...

I should say that 3/32 would be marginally better (got my eyes on a particular chain) but 1/8 would be ok if that's all that's going.

Wow, that was fast :) Cheers, man.

TDV had a bunch of lock rings a couple of days ago. I was walking by and they are still having the sale. lots of bb parts for pennies.

Thanks for the heads up, but I should add that I've been a tit and not clarified that I meant the South of England (ie. Bournemouth), not South London :) sorry

Ive got a bb lockring aswell, I can stick it in an envelope and post it to you i you like

Okay, by the looks of it the BB lockring is sorted, anyone got a 15t cog lying around? :)

Cog (probably) found, thanks all.

Me again. No luck on the cog, so I'm still looking for a 15 tooth threaded cog, posted to Bournemouth. PM me or post here if you've got one in reasonable condition.

PS - just to clear up any potential confusion, I'm not looking for a freebie :) I don't really want to spend more than £10 on the sprocket. For that I can get a pretty low end Gusset or suspiciously unbranded one new, but if I could get a nicer one used that would be better. I'll leave this thread for a few days more then give up.

PM Me, I've got a Dura Ace 3/32nd 15T, let me double check. If not I do have 5-6 1/8th 15s

Both bits found, thread closed.
