Dear Experts:

According to the Aaron Davis book, Mauser stopped rust bluing Lugers when they took over the DWM production in the early 1930's, and then finally did away with strawing small parts in 1937. Other sources seem to say that Mauser used rust bluing on Lugers all the way to 1937, and then switched to salt blue at the same time as it eliminated strawing. Which is right?

Thanks,
Jeff
