new chain old sprocket?

Yes that's something I'd considered but as I said, it barely looks worn. I can grab photos if useful. I guess they must wear quite quickly being so small, but still...

Unfortunately I've just placed my annual SJS order or I'd get one anyway as a spare

if you didnt replace the sprocket, 100% thats the issue; is it is BSR hub? 13t?
