And can not this be a memorable sign of the cross, dedicated disabled Sinop battle ...

Participants of the Battle of Sinop received a medal "In memory of East War" (something not particularly rare, inexpensive, often found on internet-auctions). Information that was some other insignia of this battle, have not met in one source.

Another possible "footprint" - in the history of the Russian Navy are several ships named "Sinop"

Also inclined to this version. All luck!

"To let Turkey in this matter" - is unlikely, although this practice has been: fence Transfiguration Cathedral in St. Petersburg made from captured Turkish guns and still stands today. But a year after the Battle of Sinop, almost all Russian ships participating in it, including the flagship Nakhimova - Empress Maria, were flooded in the Sevastopol Bay in order to prevent thither Anglo-French fleet. Perhaps wishing to honor the memory of these heroic ships, and decided to make a memorial crosses?

Unfortunately, it is all just conjecture, by topic veronika is silent, and yet could say anything about the history of falling to her of the cross ...

Of the captured Turkish coins in Russia and the salaries for the icons do. I have such an icon.
  Trial of Turkish silver called - "levok" - from the name of Turkish coins "BGN", sample 72nd, sushestvovala long before 1740g.
But later found occasionally, until the end of the century.
