I'd agree with Mike and JF above. 3610 is rare enough, a Max of two years in production. All they are is a glorified 3600 with a poorer gearbox. It was replaced by the 3910 which had double reduction backend.
Would know of a few 10 series with Fritzmeir cabs, all the first range though. Once the AP and LP cab from Secura came along that ended them. Although there was another cab sold on a lot of later 3910 and 4610 tractors which is Fritzmeir like and that seems to have been for the Irish market only.
An example here.
