Great stuff Bruce & Bolleken !speedgraflex wrote:Bolleken provided some very helpful information today! Thank you, bud. Here is a snapshot of the progression of A-1 to A-3 profiles. The black "eagle wing" comes with version A-2. This is not definitive by any means. However, in our line of work we often go by the best available information, so I am going to blacken the sides with exhaust and not paint. I feel better making this decision.
Within the same information here is useful information and very very very useful blueprints with rivet patterns.
From which book is this ?
