These are looking really good! I think 2.75 inches in height is right which should include a slightly round nub at the peak which is missing on your beacon and that detail is visible from the BF cd JP closeup. The stabilizer is at 1.5 inches in comparison and has diagonal criss-cross hatch detailing around the top 1/4 inch area.
Indy,
Could you post a pic of the "nub" for me.........:confused
Or edit this pic with an arrow ?
