Here we have examples of the smaller fin units.
A quite scare restored one from an SC70kg bomb case. Note the mounting holes halway down the cone.They are for the spigot on the bomb case,being longer than a 50 therefore the design different. Slight markings can be seen(44).Need a yellow stripe when time.
As for the others,they are probably classed as top grade.
Lovely original paint and great markings!
The longer(sleeved) one is from a SD50 The shape and red stripe denotes this. Made completely from sheet steel.
The others are from an SC50kg,again steel but shorter to fit on the standard case.
