    Default Perkins 4-108 ID and Reduction size?

    Hey Folks,

    I am looking at this little Perkins diesel for my displacement cruiser. I was told it was a 4-108 but don't know for sure, it is very clean-looking, painted orange. It has a Paragon trans and reduction gear on it, but I do not know the reduction ratio. Is there some way to determine the ratio, maybe by the diameter of the case? I can find no tags anywhere.
