This is an early variation of FED 1a with smooth covering instead of textured vulcanite. The example shown may have a non-origonal, replaced covering, as existing photos and examples in collections have a smooth black covering that is much less shiny, showing an almost matte surface (please see the black and white archival photo).
This cover exists on others FEDs to. No. 491 and 607 has the same.
