Here's my Hasag polar 11A bought some time ago. The condition was good, only rust on the donut tank. The globe and the spirit cub are missing. I gave all the parts a good cleaning and replaced the seals for new ones. The missing spirit cub was a problem, so I decided to make one myself. The cub I made is from a stainles steel ashtray. The dimensions were perfect, and the cup worked very well. The missing globe is replaced by a globe of Petromax 834.
