Bought Me A 175mm Petzval Lens From Poland

Not sure if this is a good 175mm buy lens or not, but the seller from Poland wanted $225 USD for it with only $15 USD shipping. I offered $165 USD and was accepted. I figured it was acceptable low ball offer on my part. A buy of some  but minimal risk, will see where  it leads. I hope to use this lens to do 4x5 ambrotypes and  glass negs with my Korona camera. A petzval style lens with a working aperture and flange for $165 USD can't be too bad a deal. Not sure of the max aperture (f3?f4? f5.6?), or what a picture made with this thing will look like. That is usually a chance you take when you buy old brass lens.  I hope this lens has a really cool swirly look. If it does then this was a great and important buy. One of those deals where if I get 1 or 2 good ambrotypes/negs out of the deal it was probably worth it.
