My 1900AE came with an original wooden bottom, but it was quite damaged and had chunks missing. I asked a member of the forum to upgrade it for me with a new bottom. A new spring may have been added; I don't recall.

I have a couple replacement wood bottoms from various sources; they may or may not be to "Luger specs". The one in my AE mag may be thicker in the spring pocket than an original; the spring may have more coils, whatever. Eight won't go in.

I have several sets of Wolff springs, but I don't have an original to compare them to, as to wire diameter, number of coils, etc. But I have noticed that Wolff spring wire diameter is not the same as German (or Japanese) wire diameter [Metric?].

There also seems to be no standard for measuring spring weight. Some mfgs express it as the weight required to compress the spring one inch; other mfgs show it as weight required to compress to coilbind. I don't trust any of Wolff's measurements. But they're new wire which is a big improvement over 70+ year old wire (or 110+ year old wire).
