ruling for scrap orthros

Scrap Orthros

This card cannot be Normal Summoned or Set. If you control a face-up "Scrap" monster, you can Special Summon this card from your hand. If you do, select 1 face-up "Scrap" monster you control and destroy it. If this card is destroyed by the effect of a "Scrap" card and sent to the Graveyard, you can select 1 "Scrap" monster in your Graveyard, except "Scrap Orthros", and add it to your hand.

so can scrap orthros be sp using scrap chimera or monster reborn, summon priest etc given that it has never been sp properly? i.e sp when there is a scrap monster and destroying a scrap monster when sp-ed

of course
