Antique Pink Lustre Cup and Saucer - Marked 1136

I picked up a couple of pretty antique cups and saucers this morning from my favourite market stall. This one is a lovely shiny pink and copper lustre ware design, which I think is often called Sunderland Lustre Ware, though it is probably made in one of the Staffordshire Potteries. I did find one attributed to Harris and Goodwin but I can't find much about this pottery ( It could be Goodwin Harris!). I think it dates from the early 1800's to maybe the 1850's, but I can't quite decide how early it is! There seems to be quite a few around in this pattern.
