3 x vintage chromed SAR/ SAS lights

3 x vintage chromed SAR/ SAS lights. I am not sure where on the train these lights originate from, but they are clearly marked. The 3 lights are marked as follows:

• The first has "Heklaterne, H400, PB, 10W, DHI 02.01.72" and is numbered 425643. It also has Duiker, SAS/SAR and 10.3.75 on it. It has a clear glass - clear light. It is rounded in the front, and measures 9cm x 10cm.
• The second has "Backbord, 5Bb 400, PB, 25W, DHI 02.01.72" and is numbered 411735. It also has Dolphin, SAS/SAR and 10.3.75 on it. It has a red glass - red light. It is rounded in the front, and measures 9cm x 10cm.
• The third has "Topplaterne, T400, PB, 25W, DHI 02.01.72" and is numbered 414059.  It is rounded in the front, and measures 9cm x 10cm. Unfortunately the glass is broken on this light.

I would loosely interpret Heklaterne to mean gate lantern, Backbord to mean back plate and Topplaterne to mean top lantern.  The 3 are in fair condition for their age, except for the broken glass on the third light. A great buy for the collector of railwayana.
