SF-2 (Tesla Pančevo)

Photos show starters of the same brand. I bought the metal starters in 2017 and the plastic ones last year.

A bit of history
During the sanctions, Yugoslavia used starters mostly assembled from ready-made ampoules made in Russia. The plastic models have a slightly smaller ampoule, similar to the one on the picture. The reason was that the economy was weak and under sanctions.
The picture shows a defect in production (SF8 was marked out instead of SF2). The glow color of the starter varies depending on the gas inside. Metal starters SF2 glow blue, plastic SF-2 - greenish blue.
