quick thing to point out before ordering…
the PI instruction relating to banners states
the Banner shouldn’t have a badge in the top corner, however if you speak to your WingCo he can give you permission. I would get it before ordering as some people are VERY pedantic!
don’t think you need the brass bucket, again check the PI
I’m going to go against convention and recommend Flying Colours Flagmakers. They have done really good work for us in the past and will do what you want, as well as supply all the extras if necessary (not sure on the leatherette drill bag).
They will likely be much cheaper than New Newton with no discernible loss of quality. It wouldn’t hurt to get a quote from multiple sources anyway.
