Possible Age and Pricing?

[starmount1]

I have this old Rothenberger Pipe Flaring tool that I would like to sell. I think it is from the late 60's or early 70's. The dies ..if that is what they are called..are in great shape in the original box.  Looks like made in Germany. 

Thanks in advance!

seems it spared installation of elbows, connecting pieces etc. when widening to the measures of the next tube by directly brazing. 1967.
