Hi Fernando
Yes, the chain came with the measure. (Wish I could find a source for chain like this).
The modern day versions of these measures are marked 20, 30, 40, etc. up to 120. With marking in between these numbers representing 5 grains of black powder.
So the marks on these originals have to be something similar. I'll just have to take my new measure and do some experimenting. Will report back.
Notice the markings on your measure is identical to mine.
