I'm looking for a good deal on used, decent shape 54/75 mm Aerotech, CTI and/or AMW hardware. I have some but here's what I want for next Red Glare in Oct

Aerotech: 54 mm 1706 & 2560 casing + 54 mm seal disk
75 mm closures + 3840 casing

CTI Pro54-6G or 6GXL Case & rear closure
Pro75-3G Hardware set

AMW: 54MM 2550 all hardware
75MM 3500 all hardware

Also reloads for above in the 2200-3500 N-sec Impulse range

Thanks in advance
