What is this?

I bought an airplane mechanics tool box a few years ago and was getting some tools yesterday and found this tool and I'm just wondering what this is used for?

It's a push rod housing installer sold by Gibson Tools in El Reno OK. Used on a few Continental engines

Wow thanks for the info, kinda pricey isn't it.
