Thank you kindly for your assessment. Glad you like the final results. The rubber flaps were made from a material i had collected from a dumpster, if i remember correctly. Don't really remember from what object, as it was a really long time ago. I usually collect lots of junk, for possible future builds, and this was one of them. It looks to feel like nylon, but not sure. I cut up the pieces and painted them black and weatheted them. The final results is what you see.
Glad you approve. Thank you.
