Hi Ron,
Nice looking LP-08...1917 is that odd year. I think they start out with both fine-tune adjustable front and rear sight, then switch to a fixed front sight and the fine-tune rear sight, and then finally fixed front and rear sights. If I recall correctly all of the 1918's have both fixed type sights...only.
Maybe George Anderson or others know the serial numbers (i.e. ball-park) at which the 1917's started to change....
Regards,
Pete... <img border="0" alt="[typing]" title="" src="graemlins/yltype.gif" />
