10 cylinder, 5*2 radial engine

We’ve found a 10 cylinder radial engine that we are trying to identify. I’ve looked at some of the images of Anzani engines but they have what looks like a hemisphere shaped cowling that this engine doesn’t. However we thing the stroke is about 14cm which matches information that I’ve found,

Photos are a little hard at present due to its location, but we have some measurements to compare.

Are there any resources on the internet that show dimensions of the anzani 10 engine we use to check against?

thanks
