I'm not sure exactly what type except the handle says Wright 333R. It was in a closed package with no label on it. It was in similar things of my father's from the 80's and 90's but not sure on time frame. I had to open it as I couldn't tell what was inside so I took pictures of all of it. If you have any questions, please feel free to ask. Seems to have everything as there is a small crack in the plastic of the original packaging. Checked the keys and they both work perfectly.
