Need somewhere from 500-2000 of these fin assemblies in steel or aluminum for display only, no military use. I think the tube part can be made on screw machine and the four fin pieces are stamped then bent. Or whatever, however, we’d like to get them for $5 to about $10. Ea. If possible. Quantities we order depends on price. Where should I advertise our formal RFP to get bids? I do have a complete drawing but much too large a file to post here.
