Did some more digging and happened across the archived version of the document about astrolabes that was actually linked to with "Astrolabe of Berselius". 

That document, as alluded to in Stephan Bax's post, mentions another astrolabe containing "jong". Well, turns out that it's the Sauvaget Astrolabe! Theres actually another side to that astrolabe that isn't included in the JSTOR image set which has another set of the months, and a "Hollande" to go along with our "Engletiere". 

   


   

They actually work out the rough provenance You are not allowed to view links. Register or Login to view.:

The inscriptions on the plates of the geared astrolabe (#198), the front and back of which are shown in Fig. K.6. Although the plates are clearly intended for use in South-East England and Holland, he horary quadrant on the back is for a latitude which would serve Picardy. Where the instrument was actually made remains a mystery.

The geared astrolabe in the Science Museum (#198) has a plate serving engletiere on one side and hollande on the other (Fig. L.6). The double horary quadrant on the back, however, serves a latitude of ca. 49;30°, which seems to localize the provenance to somewhere between Southern Picardy (Amiens) and Eastern Normandy (Rouen), but it could also be, say, Reims.

So this source claims that it is likely from northern france (Picardy/Normandy), and would have been used in south east england and holland. They also state that "It has been dated as late as ca. 1500 (by Robert Gunther) and as early as ca. 1300 (by Derek Price). I would date both the Picard astrolabe and this geared astrolabe to the 14th century, early or late I am not sure"
