I've no idea where my copy is, but the Benjamin Harrison Optimus is featured in R.L. Wilson's book "Steel Canvas". I had a chance to see and handle that gun years ago when it was on consignment at the now defunct Atlanta Outfitters; it was a beautiful gun, but in my opinion not as stunning as the Linneman Optimus featured years ago in the DGJ (2001?). Although I've never seen a signed piece, at least one member of the Glahn family engraved for the Syracuse Arms Company based on pictures of pulls found within family archives.
