Videos of the day (2): Lazam Najd, Suwayti al-Hafi

Two other Youtube videos from the same provenance, show the handsome desert-bred stallion Lazam Najd, a Suwayti al-Hafi by strain. He is a son of the Hamdani stallion Haleem, featured in an earlier video posted here. This is the first time I hear from the strain of Suwayti al-Hafi, although I am familiar with that of Suwayti al-Firm, which was the marbat of Muhsin al-Farm, the Shaykh of the Bani Ali section of the Harb tribe. Suwayti al-Farm is one of the mains strain currently represented in Saudi Arabia. But what is Suwayti al-Hafi, the strain of Lazam?
