The Cathedral Treasure

[amena]

Hello everyone
I was asked to identify the hallmarks of some objects in the cathedral treasure of my city.
Among the objects is this tankard, which seems German or at least central European.

I can't decipher the hallmarks.
Can anyone help me ?

p.s.I know that I should embed the images, but at the moment postimages doesn't work and I don't know how to do it with Imgur

why not russian?

No, nothing indicates Russia here.

I agree. Nothing indicates Russia. The carving could depict Holy Roman Emperor Charles V during his coronation procession in Bologna in 1530 and the person wearing a mitre could be pope Clement VII (one of the first bearded popes). This was the last time the pope crowned an emperor in Italy. I managed to find this tankard online and it's indeed located in Bologna. Apparently it features Lambertini coat of arms in connection to the donation. It would be interesting to find out if there's any additional info about that. It's also stated that it's from the 16th century. I'm not familiar with hallmarks of that period but especially 80 seem rather strange. Is it possible that the silver framing is later or perhaps repaired and hallmarked then? Or if the donation was made in the 19th century could it be from that period instead?

:::: There seems to be something above that "80" hallmark, what could that possibly be? :::::::

:::::::: We had a thread talking about the usage of dates in 16th/17th century Naples & Denmark silver with full dates like "1608" and "1580" so is it possible that we are looking at a date such as "1580" or "1680" and the first 2 digits have simply been cut-off for some reason (an uneven strike of the hallmark punch?). :::::

::::: And I still think I see something above that "80" hallmark. ::::::::::

Of course, this is the solution: a replacement. The marks are Roman and can be dated to the time of the papacy of Benedict XIV, Cardinal Lambertini (1740-1758).

The mark .R.C.A (reverenda camera apostolica) and the mark 80 which stands for 80 baiocchi (711/1000 at the time) are recognizable.
The mark AK is not in any repertoire, so it is an unknown silversmith.
However, it is known that a goldsmith named Batdassarre Kriegl was active in Rome at the end of the 17th century. Could he be a descendant of his?
In any case, the initial K of the surname suggests a silversmith of foreign origins.
Thanks Sasropakis for showing me the way.

:::: I found an "AK" conjoined in script stamped three times on an ornate object that has a description "probably Hanau" :::::::
::::::::::::::::::: Those Hanau makers were good with the antique-style hallmarks, that's for sure. :::::::::::::::::::::::::::::::::::
