It's definitely a step up, or more accurately, nothing to do with Baikals made at the rival Izhevsk Mechanical Plant. The Tula plant was established around 1712 and eventually made mosin-nagant rifles and eventually AK-47s. They weren't really a shotgun company.
This model is an 'exhibition' module used as showroom pieces, so good engraving and finishing worthy of a more expensive gun.
There are a couple of hints to more agricultural models in the range such as the heavy springs and swivels.
Was able to take it out for a quick blast today, very smooth shooting and the coin finish is very eye catching and it got a few admiring comments.
