Vitavox ak121 driver recone.

Hello vitavox fans. I am fortune enough to acquire my first vitavox driver. Though the website is a little ambiguous I believe it is a ak121 It has 2 bolts at the rear and it's serial is 65446 It looks like the lower driver of the drivers shown when you hit on ak121 link.

For some reason some butcher has decided they would upgrade it by spreading some sort of bathroom silicon around the surround and used epoxy to firmly glue on pieces of plastic strip across the out side of the cone to strengthen the cone.

Despite this it is a very beautiful driver and reasonably good condition. No cracks good felt good coil.

Any help on its use and where or how I might find or modify a cone to fit it would be appreciated. I would like to find a mate for it too of course one day luck permitting. It seems like a driver suited for midbass horn duty's. Does this sound correct? If I cant find an original cone I may attempt to make my own cone for it.
