Hello All,
Found this little beauty yesterday. Pretty elaborately decorated with a nice scene of the past. Tray is decorated nicely also.
I was hoping the experts in this forum might know something about the tray. Any information would be appreciated. As a side, I am not sure if it is Sterling/Silver or Silver Plate. Don't want to mar the piece to test it.
Any suggestions?
Thank you all for your time and efforts in advance!
Sincerly,
Chuck

Four marks on front left side under the jug...can you do a close-up...might be Hanau pseudos or real marks.

Hello All,
I am absolutely impressed. You have eyes of a hawk Traintime, amazing! Wolf & Knell it is, thanks for spotting those hallmarks. Exact.
I'll try to take a close up for you tomorrow when we have some sunlight to get a clear shot.
Thank you for your time and expertise!
Sincerely,
Chuck
