Hi guys ,
I have got 2 rope blocks one is original and the other I am not sure .
I heard there are 2 versions are the ones on the pictures correct?
And what are the differences.

Peter,

I have 2 rope blocks, there is a number 8 stamped on both sides.
Not shure if these are originals for GPA or waterweasel M29C:

Peter/Leo,

I have the same type of snatch block as Leo with the letter 8 on both sides and what appears to be the outline of a capstan winch opposite of the number 8. I can try and post a picture later this weekend.
