Hello, i'm new here and have just bought my first piece of antique silver.
I Believe it to be from James Dixon and sons and marked Sheffield 1887 but i'm not sure what the numbers and letters on the bottom mean?
any info would be great thanks!

Hi,
Welcome to the forum. Good luck with collecting silver. The tankard is nice.
You are correct about the maker and the year.
Numbers are manufacturer’s inventory or serial numbers.
Its capacity is ¾ pints (PT).
What`s the weight of the tankard ?
Regards

Hi,

I would assume the 6.65oz mark refers to the weight of the tankard, if it was for fluid ounces this would be less than half a pint.

Dear Martin,

I would assume the 6.65oz mark refers to the weight of the tankard

Exactly! That`s why I asked for the weight. Fluid ounces (6.65) are not matching three quarters of the pint (Imperial British measures).
It`s definitively not a measuring tankard (having in mind elaborate decoration). On the other hand, it can be used to measure the capacity and weight of any dry stuff put into it if the weight is known, being 6.65 oz.It`s not seen too often in nicely decorated tankards, so I am really interested if you could provide its weight. If it`s 6.65 ounces then we have the answer.

If it is the weight of the silver, it is presumably a measurement in Troy ounces to which a measured weight in avoirdupois or grams would need to be converted.
