Sentry Bot Model (Fallout 4)

The sentry bot model is a miscellaneous item in Fallout 4.

Characteristics
A small, collectible model in the shape of a sentry bot. Though this item appears in Fallout 4, its design is based on the Sentry Bot from Fallout 3 and Fallout: New Vegas, a trait which is shared by most collectible models in Fallout 4.

If you attempt to sell this item to a vendor, you will receive the message: "You cannot sell quest items". This would seem to suggest that it may be used in a quest somewhere, however, they can still be stored in containers. NPCs may steal the item if left unattended in settlements.

However according to the Vault Dweller's Survival Guide (Page 91), the models are all "knickknacks" to decorate your home with or to be sold, no mention of a quest.

Locations

 * Found randomly in a Vault-Tec lunchbox
