Herb,
There probably is no way of knowing. I suspect that the magazines in the 1906/29 Special Assembly were just like the standard 1929 Swiss magazines. Of the three 1906/29 pieces, photos exist of 33090 (Lugers at Random, Kenyon) and 33092 (Monograph IV, The Swiss Variations 1897-1947, Datig; and Parabellum, A Technical History of Swiss Lugers, Bobba). In the photos in Kenyon and Datig, the magazine bottom piece is "plastic" (black bakelite) but there is no way to determine any markings. Serial number 33092 originally belonged to Datig and it is interesting to note that in his picture from about 1966 the magazine base is bakelite, but in the more recent picture in Bobba the magazine has been replaced with one having a wood base. According to Bobba, there is strong evidence that 330933 and 33094 also existed.
