Hello Don,
The Swiss Bern factory made some "transitional" lugers between their 06/1924 model (a P-08 model) and their later 1929 model.
This luger had the top of a 1929 on the frame of the 06/1924 model.
According to Vitorrio Bobba's book, The Swiss Parabellum, these transitional lugers are quite rare...
I will be home this weekend and will plan to scan a photo or two from this book..
It might be worth going back to Austin for a second look...if this gun is a Swiss transitional piece, at $ 999.00 it would be a tremendous buy...
Or it might just be a "parts" gun put together from some P-08 and 1929 Bern parts. <img src="graemlins/yltype.gif" border="0" alt="[typing]" />
