Fed 2 with lens cap inscription.

Thanks to Vlad translation (thanks, Vlad !) one can read :
" To Nikolay Sergeevich on the birthday from workers of Soviet RKKPU"...

RKKPU - Районний Комитет Коммунистической Партии Украины. -
District Committee of Communist Party of Ukraine.
Soviet - is name of the district.

Fed 2 s/n # 3480014.

Food for thought: How do we know that the lens cap came with this camera? (Nathan Dayton)
