Looking for old record seller lives in Haringey?

Hi,

I am looking for a gentleman that lives in Haringey, I think possibly Crouch End, that sells or has a big collection of  old vinyl records to sell.

I spoke with him once but I don't remember his name. At the time, he was looking for an event where he could sell his records.

Please let me know if you think you might know who he is and how I can get in touch with him.

Thanks

Ana
