"Avstock about" likely refers to either Avstock Aero Assets Trading, an aviation asset trading and component supplier based in Dubai and Singapore, or potentially A-Stock, an online marketplace for he
avily discounted merchandise that holds weekly auctions. Other entities like Avstock Zen Private Limited (an Indian agricultural company) and A V SHARES & STOCK BROKING PVT. LTD. (an Indian stock broking firm) also exist, but the context of aviation assets from a company named "Avstock" makes the first option more probable for the aviation term.
