Testing for lead

The cabinet of my 1907 model 27 Singer Sewing Machine is yellow. Hm. Pinging online groups, there is a general consensus that they didn’t come in yellow. Prompted, I looked at the hinges, and yes, the hinges and screws also had yellow paint, so someone, during the life of the machine, had thinly painted it yellow. Sigh. The next question, how long ago? Was there lead in the paint? I purchased a lead test kit, followed the directions, and happily, no pink. If the swab or surface turns pink or magenta, it indicates the presence of lead. Since it isn’t lead paint, and it is not original, when the weather cools off here I’ll strip the paint and refinish.
