Thanks Rich, That should work just fine...Closest will be a 5:1 nosecone, the PNC/BNC-50Y is a 4.45:1 ratio and it looks to be a somewhat standard ogive nose cone. MAC Performance and Giant Leap Rocketry both carry the plastic Pinnacle Nosecone which is a 5:1 and would be a close match for the 50Y. I like Pinnacle nosecones fairly sturdy but much lighter than FG.
I recognized it immediately... Nice Job on the upscale.I modified your file. I changed it to the 54 mm LOC mount
