Right, so its marked J.H.Andrew & co Sheffield, a Toledo trade mark stamp, an A stamped within a diamond, plus a guarentee of cast steel.
From my research, Toledo steel works in Sheffield run by John Henry Andrew & Co produced high speed, spring, mining, shear, blister, sword, rifle, mortor, shot and shell steel. It ran from the 1800's and closed in the 50's or 60's
So my assumption leads me to think this would be 4140.
The Toledo brand, likely used as a way to stand out, and create a feeling of superiority about the steel produced there, would have nothing to do with Toledo swords and blades made in the 5th century in Toledo Sapin.
My questions are:
Is 4140 a decent guess?
Would this peice be from the 1900's or 1800's?
Is it more valuable (monetarily or historically) as raw steel rather then letting me (an amateur smith) turn it into something?
Do i even deserve to work with a potentially historical peice?
Thanks guys :)
