Badge for food preparation units (?)

Bronze, stamping, enamel remnants. The sheaf, rake, scythe and sickle on the applied element of the presented badge, in combination, were the emblem of agricultural secondary educational institutions (before the revolution). In the Red Army, similar symbols were found among labor armies engaged in agricultural work, however, the presence of a wreath and shield, identical to those of the police, suggests that this sign belonged to the RCM units associated with food preparation. We will be glad to hear your comments on this topic. Badge from the ground, original twist. Authenticity guarantee.
