Malaysia - Registered Cover (Jementah)

I bought this cover some time ago from a stamp dealer. I quite like the cover because the postmarks are clear. This cover was sent from Jementah on 16 August, 1980 by Loh Yok Sin (Jementah) to International Postal Auction (Kuala Lumpur). The cover travelled to Segamat (16 August, 1980) first before arriving at Kuala Lumpur on 17 August, 1980.
