I have had a good bit of luck lately on the local internet flea market. Found another nice old lamp and it arrived at my place yesterday. This one looks like a real Hasag 351L, in what I suspect Wehrmacht colours. I would appreciate some of our German members to give some advice on this. Tank is steel, and I was very worried it would be full of holes. However it is in good shape. The whole lantern looks like it has been cared for. I will get some more pictures uploaded when I get started with the clean-up.
