Some mystery sirens in Israel and Greenland

[CactusOrAxel]

The mechanical sirens in Greenland are made by Carl Th. Malling A/S.
Company is now defunct, but many still remain.

Sorry for the bump.
These are all by the company known as Carl Th. Malling, later Malling Kontrol and now DEIF A/S.
The siren in Greenland is also a Carl Th. Malling siren. I refer to them as Type A and Type B, as there are two different sirens with two different ports. I believe they're called something along the lines of V4DSL without being 100% sure. I hope to be getting a similar siren to these soon where I can verify all facts.

Hope this helps.

PS. DISA made the E37, E37D, BD8, LS8 and LS8D, (and a couple of other ones which I'm not totally sure on).
