TRADES Highly Educated Control Tower TRADES

Alright it’s the Highly Educated Control tower we all know and love. I have 2 new in box, the SE pillar is still sealed as is the banger. It is a 10mm 90degree and I’m looking for either - same exact banger except 55 degrees. I’d also be down to trade for a different american brand in 45. Also, like I mentioned I have 2 NIB control towers so I’d also be interested in a different style 10mm 90 banger. Let’s help each other expand our banger collections!
