First of all, many thanks for the helping!
Second!, what it means "hallmarks"? Could you put a photo or drawing as a reference? sorry but English is not my native language!
this is the base of the Tilting Pitcher, (the circle) it says
"MF'D & PLATED BY REED & BARTON
144"
it is marked too a number "365"
in the cup as in the base, says
"MF'D & PLATED BY REED & BARTON
1866"
No more numbers or anything else
and some pictures of symbols and things
Really appreciate all the assistance and help! THANKS!
