Folks,
My used (eBay) E61 machine came with 4 portafilters. 2 were proper, original equipment to the machine, and two do not work with my Bunn ES-1A. The locking 'ears' are at a different angle than the stock ones, and my standard 58mm baskets are just a tiny bit too large to fit in them. I'd ultimately like to sell them, but it would be helpful if I could first find out what machine could accommodate them. I'd appreciate anyone's input.
David
