Yes, actually the British museum has a full set of navagraha sculptures near the rear (Montague??) entrance. They are on the left side along the wall. They’re 13th century from Odisha. I’ve attached a folder with photos I took just last year for my own dissertation work on jyotiṣa. I can't seem to find them on the British Museum website - perhaps I'm not searching correctly or they're simply unlabeled. These photos should come through, but please let me know if they don't and we can use a fileshare site.
Thanks,
