I'm looking to make my own Cantel for a dress sporran and I nee all dimmensions. If it is at all possible to superimpose the dimmensions over the top of a pic of a finished dress sporran with a cantel?

Im trying to get rough measurements and construction.

I work in a machine shop and the material and shape shouldn't be too difficult to overcome, however I don't know about sizes at this point.

Many thanks in advance.
