Enlarger Identification

Hi All,
I'm on the process to grab this enlarger equipped with Ilford Multigrade head and easel, but I don't find which base / model is it...
It seems similar to an agfa varioscope, but not it... if someone have any clue!
thanks!

Finally I've found which enlarger it is. It's a IFF Duogon 6x9 enlarger base. Not very common!

I have an Ilford head mounted on an Omega D2 chassis. It works really well on the Omega, if you want to move to a more capable chassis.
