37 chief coil mounting question etc.

[Paps]

Trying to help a fellow enthusiast out with his twin 37 Indian Chief. The coil mounts in front of the engine which is normal for these bikes but in 1937 there appears to be another part mounted over, near, or with it in pics I have looked over for him that is not found on the other years and models. The pics are not clear enough to get a zoom in look at it. He told me that the 37 had something extra in the coil area but he cannot recall what it was. As an owner of several Indian models and years, he is pretty intelligent and knowledgeable on Indian bikes. This particular senerio stumps him. In order for this fella to put his bike together correctly he needs some closeup pics of the coil area on a 37 twin Indian Chief. Pics of the exhaust mounting are needed also. Any and all pics and information would help. Thanks in advance, Paps
