Crichton Bros 6 Piece Sterling Silver Tea Set

Hello,

I recently acquired a 6 piece Crichton Bros silver tea set and I was wondering if anyone would be able to tell me a little bit about it. One of the photos shows has the hallmark visible, and another shows the bottom Crichton Bros stamp for each piece. There have also been some numbers etched in the bottom as well.

If anyone could help me out it would be much appreciated.

Thanks
