Help with Coast Guard Decal dimensions

To be honest Aaron I'm not even sure. These will be used on custom fishing rods for some coast guard retirees. I would think i need the overall logo diamter to be 3/8"-1/2" max for it to work. I'm not sure what scale that would equal in model terms. 

Why not reach out to Joseph at Fireball Modelworks himself?  He is a great guy and is usually willing to help.  I know he has scaled decals up for some, such as a custom 1/35 Jayhawk project.  Can't make any promises, but based on personal experience, his product quality and customer service are outstanding!

I can't help being reminded of a model contest in which I served as a judge about 25 years ago. (That was the last contest I ever had anything to do with; I really don't believe in such things any more.) It was held at a small maritime museum in Massachusetts, and offered a special award for the best model of a Coast Guard vessel. One of the competitors had a small Coast Guard logo on each side. Back in those daysI had excellent closeup vision (I don't any more), so, unlike the other two judges, I could read the small lettering on the circle around the shield. It said "Union Pacific." The ingenious modeler, needing a tiny CG emblem, had wound up the the model railroad department of his hobby shop. (The emblems for the Coast Guard and the Union Pacific are a lot aike.)

I had a couple of models entered in the USCG Bicentennial Model COntest at the Customhouse Maritime Museum in Newburyport, MA in 1990.  USCGC CONFIDENCE (WMEC 619) and USCGC VIGOROUS (WMEC 627) were in the same case - I served on both cutters.  My other model was the small Dumas USCG 4i' UYB with a freelance paintjob - gunship gray with white markings, red & blue stripe and shark mouth & eyes at the bow.  Paint job was based on a picture of a USCG 311' WHEC painted gray during Vietnam; and a second picture of a 41' UTB with the shark mouth.

CGBob, that contest at Newburyport was the one where I spotted the Union Pacific logo in the middle of a Coast Guard emblem. I was one of the judges. The Coast Guard covered the expense of the trek from North Carolina to Massachusetts. Small world.

I hope the model with the Union Pacific logo wasn't one of yours. If so, I now have a size 10 mouth.

You probaby know that Newburyport was the site of the building and launching of the Continental Hancock. And nowadays Newburyport is the home of the A.J. Fisher ship model manufacturer and dealer. And a pretty nice, real New England town as well.

You could make your own decals. Use this image: http://polarfield.com/barrow/wp-content/uploads/2011/03/USCG-Emblem_approved-version.png

Make it any size you want, then print it on white decal paper.
