Looks to me that R.W.P. got a little cheap as they probably charged by the letter for the engraving lol. This might be post Civil War ? I have a similiar sword ( naval model 1852 ) presented to Joh Dean Mulligan of the USS Miantonomoh from his( Messmates) Spanish American War who oddly enough was listed as a pharmacist. Beautiful sword to be proud of and hopefully by chance you can identify this some day .
