DSO “Aircraft” Hose Clamps

[brinkjm]

I’ve seen this option listed on a handful of Eminger invoices from 4-eye cars. What exactly are these? Worm type? T-type? Spring style?

They can’t be all that special as the invoices show them as a whopping $6/$8 option 😂

When considering a correct restoration, would standard worm style clamps suffice? I assume the clamps are for radiator and heater hoses.
