Please look at http://home.comcast.net/~markconrad/Toledo/Page1.html
for photos of what appears to be Ohio National Guardsmen c. 1905. Their hats have STK (or TSK depending on which letter you begin with). Does anyone have any idea of what this unit is? The Toledo connection is based on the marking on the cardboard picture frame. So "T" could be "Toledo". Since there is a Polish name associated, could "SK" be Polish for Rifle Corps ("Strzelniczy Korpus")? The uniforms and accouterments are good, in my mind too good for a private rifle club, but maybe that's what this is.
