1835 R.Wallace

I love to collect flate ware, this is just one of many that I adore because it was given to me by my Oma over 35 years ago.I Have many sets now - but only know what people want to pay for them and I can't sell . This one above was my Oma's !! But, if anyone knows about it please tell me! I'd love to learn more ;) I did find out it is from 1835 and that is why there is no markings - only the date and name. It's called Nickle Silver but R.Wallace sure did come out with some fine sets after! I love Lady Doris as well as many others!
How do you think it should be cared for and do you know where I can find more originals? Thank you so much!
