Silver plated lidded container

Howdy all don't generally buy anything silver plated anymore but this took my fancy especially with the birds.
Gave it a polish and the outer layer seems really quite thick I scratched one section 5 times and was still coming up red nothing is flaking on the outside a little in the inside.
Question is what type of container is it and does anyone have an idea on age. Its 220mm across with an x and 370 stamped on bottom. Did a little research but trust you guys more so. Chris

 

At that size, perhaps a tea caddy? (Or does it seem big enough for a biscuit jar?)

 

Looks like 00 with a 37 struck over it, and then the X.

 

I can only see the 00 as well. Hand wouldn't fit in for a biscuit container tea caddy maybe thanks for response c

 

It is lovely, Chris, I can see why you bought it. It was made in the Aesthetic style.
Maybe for someone with high sugar consumption?

 

It could be used for a number of things, but methinks it is a sugar bowl. The Victorians and Edwardians had large families, and one must consider the amount of porridge the children consumed.

 

Thanks all appreciate all comments

 

It isn't just family sized: back in the day, sugar was sold in blocks which one broke up. Hence big sugar bowls.

 

Ok so sugar bowl are we talking mid 1800s maybe

 

Late 19th century.
