I thought that that one had the option. There cannot be that many 195’s left with your engine. Oddly enough, the 195 is the first aircraft that I was aloud to “set hands on” while flying (which was the first stumble into a life of ruin, ending in Boeing).
Be careful with what you allow your children to play with!
The turbo version was an aftermarket add-on (STC) and was re-designated R-755-S....there are more around than you might think...and we all know each other...well almost! You can tell a turbo by the exhaust high on the right side of the airplane with the normally aspirated engine having it's exhaust exit on the bottom left...but back to the point the Jacobs L4MB or dash 9 of 245 HP used on the Bobcat was also used on the first 195s
