Bought Me A {MINT!} Lens INDUSTAR 51 f 4,5, 210mm For Large Format Camera

Bought an old Soviet era lens from Kazakhstan tonight, an INDUSTAR 51 4,5/210, cost was $190 CAD plus shipping. I saw a close-up headshot made with a similar lens had a great depth of field for the portraits, just the eyes in focus. This lens covers 5x7 and I am told 8x10. Will try to do 8x10 Ambrotype portraits with it.
