Images of Asbestos Insulation? And Asbestos in Mortar?

Does any one have any images of asbestos insulation? Client declined to pay $50 to have an asbestos test done on attic insulation because it looks like fiberglass that was torn apart and scattered.
Do we have an assortment of images that are actually known asbestos insulation? Google has too much noise.

Also, brick school building built in 1938 has PERFECT mortar joints, and it’s original. Would that make it more likely to be asbestos in the mortar? Older buildings usually have the mortar that wipes out with your finger (lime+sand).

I push testing on clients but many simply don’t care, so I recommend as much as I can in person/report and move on.
