I've had a flyer round about Holy Trinity Lennard Road's auction returning on 26th March (12 pm, viewing from 10 am), but can't find anything about it on their website (which doesn't seem to have been updated recently). Antiquities (it says!), collectables, jewellery, glass and porcelain and so on. Phone number if anyone wants to know more is 020 8778 7258.
If anyone finds a decent link, please post it.
