20 x 110 HS 404

I would like to have information on these three 20 mm
Manufacturer, model, etc.
Thank you

the black projectile with red band is a TP-T from switzerland
the green projectile with green band is a yugoslavia SPOTTER round

#2 is a Yugo subcaliber round with spotting charge. So no spotter for regular AA guns!

#3 is Swedish.

for EOD
what the type of sweden projectile ? (it had strange color)

The Swedish round here is not in accordance with Swedish military markings. A well informed friend in Sweden assumes this one to be a TP load. Your’s here might be for export. A scarce item anyways.

thank for your response

thank you for all those informations
