Hi atlas3222 -
please learn to post photos - there are several methods mentioned here!
Here are your photos:
The oklad (frame) of your icon was made in Nischni-Nowgorod around 1849-1854.
The maker is Udalov, Luka Nikolaev 1835-1848
Assayer is Savinskij Beniamin V. on duty 1847-1850
Clean (polished) silver and marks make an identification easier - otherwise it is more guessing!
Regards
Goldstein
