I found this old key it says Terryville lock company in Conn. I looked them up and they started in 1890. I sent them a picture to find out some info on it . Interesting find i thought.

Awesome looking key. With Haloween approaching that thing looks like it would open some mysterous vault. Please post the response from the company. HH Roy.
Never received an answer from the lock company but some members seem to be experts with this subject so i'll take their word for it.
It is used to pick locks. Thanks for the response
