Ferdinando, there's no need to be regretful or sorry, your posts are most interesting.
The pics in the JG300 book was exactly what I had in mind but as I was at the summer house I didn't have it available.
As you say, it's hard to talk about normal when it comes to late 109's but with all the knowledge that is beeing collected and improved, it would seem that we're getting more and more understanding of the abnormalities of different factories and versions.
