Motta 58mm flat tamper with wooden handle - £15 delivered. It's in great condition - no scratches or scuffs.
I've just upgraded to a 58.4mm, so I can post it in the box my new tamper arrived in.
For some reason I can't upload pictures, so here is a link instead: https://bit.ly/2DbolPo
I'm looking at tampers amongst a multitude of other accoutrements and I'm getting a little confused, I'm just about to replace my first (faulty machine) so I'm sure I'll be looking for a 58mm tamper but I didn't know there would be further choices regarding the base of the tamper.
