hey, i recently found an old straight razor that belonged to my grandfather. i dontknow anything about it and would like to know how old it is and if it is worth anything.the handle seems to be made of ivory, and on the blade it says "Cederlof Grunden."between these two words is a picture of a watering jug with a 10 in the middle of it.underneath that is inscribed stokholm Regeringsgat.10. does this mean it was madein sweden? on the part of the blade connecting to the handle(excuse my ignorance,i am not sure what it is called) it has "C.V. helJestrano" and "fskilstuna"inscribed on it. i dont know if you could give me any info in it, but any help wouldbe appreciated. thank you for your time
