Difficult to find example of a byf44 with both of the slide waffenamts being E/135.  This is a "p" block gun so it was serial numbered before my byf43 example with mixed (E/135, E/WaA135) waffenamts.  Nearly all of the very early byf44s have mixed (E/135, E/WaA135) waffenamts.  From there on all byf44s have the E/WaA135 for both slide waffenamts.  This is more proof that P.38s were not made in strict logical order.
