I cannot expand on wonky engraving I did not do it. After handling many thousands of all types of military arms I have seen all types of markings some so neat and some you could barely read this on stuff that had not been refinished . Refinished arms have been seen with the old markings carefully removed so you could not tell anything had been done to the other extreme of being removed with an grinder this from the same factory. twin ovoids ? different day? different man? what the machine was set up for on a previous job? just because a expert says one thing does not mean it is true
