HELP! Currently in London, UK and looking for great places to find collectors items

[imagrante]

Hi guys,

Just want to piggy back off of this topic, but I will be traveling to Paris and Rome next month and wanted to know if there are any cool stores that sells collector items, specifically the Altair bell statue and the Arno/Elise one. If I can pick them up in Europe, it will save me a lot on shipping costs. Thanks in advance!
