Nalichniki(old Russian window frames) with three-arched cover in Kovrov city

A couple of days ago I offered you window frames with three-arched cover occurring in the east of Moscow Oblast. Today, I have found this couple with the same three-arched cover, but… from the town of Kovrov, Vladimir Oblast. Curious thing is many books review patterns of window frames special for different areas, but no one traces migration of these patterns.
