It seems these days that everybody is using Ebay and I am no exception! I tend to use it to sell small items such as accessories or individually interesting records and not machines as such.
My Ebay 'handle' is 'phonoking' and I occasionally (but not always) have items listed under 'gramophones' or 'phonographs'. You can check my feedback here.
I always start and end my auctions at 8.00pm or later UK time if listed on Ebay.co.uk
I also use Ebay.com (American Ebay) to maximise interest in items appealing principally to the US market. There I tend to start sales at 9.00pm UK time to give a U.S. West-Coast finishing time of 1pm.
Finishing on Sunday, August 29th; fifteen items, mostly accessories but including two Edison 2-+ 4 minute play gearboxes for Gem and Standard phonographs.
Find them all by seeing what 'phonoking' has in 'Items for Sale'.
