Upper tang marking on my 1894 Spruce Gun|Winchester Rifles|Forum|Winchester Collector

I was comparing the upper tang markings on a couple of my 1894 carbines.  According to Renneberg’s Model 94 book, both are in the serial number range to have the Type 4 tang marking.  Both are essentially the same as far as the content goes, but my Spruce gun (serial number 849681) has a little bit different font style that my other 1894 carbine (serial number 832405).  I thought this was a little strange.  I’m assuming there were some variations in the roll dies that were being used?  Or did I discover a new style tang marking?

Here is the tang marking on my 1894 Spruce gun serial number 849681:
