Al H said:What sort of mug?
I've got two suggestions
If it was the old style mug like you sold yesterday then a supermarket own brand gravy granules lid fits perfect.
Or there is a member on here gecko who will make you one for a reasonable fee

Mr_Smartepants said:I've got a non-standard lid from the US that fits perfectly. It's yours for the cost of postage.
I'll snap a pic later.
Mr_Smartepants said:It looks just like the one in these photos here
But mine are white PVC.
If you're interested, Just PM me your mailing address and I'll get it in the post today.
