Mark,
I think the early LP-08's came with fine-tuned front and rear sights, but some came with fine-tuned front sights and fixed rear sights. Then around 1917, I recall reading, the fine tuned feature was phased out with fixed front and rear sights in later 1917 and most of 1918...
Other Forum members may have more precise info.
