Neat lock Ed. To be fair with a comparison, these two locks are really not in the same category. Thuraine was a Parisian gunmaker to Louis XIV and therefore could be considered one of the very best in the world at this time. The lock Ed has shown is nice, though of a more common quality.
It is interesting to note that on this lock a bridled pan and roller frizzen spring were employed. As to the bridled pan, it first appeared in the last quarter of the 17th century, but was used infrequently during this period. As the 18th century progressed, it's usage became more common. It must be noted that some cheaper and even relatively late locks did not include a pan bridle, so it's not good to use it as a dating feature. Further, on some high end locks, a pan bridle was likely omitted for decorative purposes at times. I'm not certain when the roller frizzen / frizzen spring first appeared, but have seen a roller frizzen on a British lock from the 1750's. Has anyone seen rollers before this? The benefits of rollers were sometimes questioned in the period and still are by some today.
