Hi Antevante, Robban and Nick
Yes a very interesting machine you have there Antevante, it is certainly a Hymac but not a Hymac manufactured in the UK.
I would expect that this was from the "Brown" era when Hymac were in their last days and trying to reduce manufacturing costs. They had machines manufactured in Italy by FAI and badged as Hymac, they also had some machines made in Russia.
The colour scheme is very similar to Hymacs from the Brown ownership and this leads me to believe that this machine is from that time period, therefore my guess is that this machine was manufactured between 1990-1994.
The design features are totally different than anything Hymac made, the back of this machine looks very much like an Akerman so the machine may have been manufactured in Sweden?
I have not followed your link to the blocket site yet but I have only ever come across one other 586s and I'm sure that was on a Swedish site.
Your best hope for details would be the dealer plate in the
cab, perhaps this company still exists but deals in other machines.
I will try and e-mail Richard Gould of Hymac a picture of your machine and ask him to forward details to me.
Hope that has been of some help to you.
Regards Jeremy
