I believe it's an SL72. I looked up the model number and it was an SL72. It's shown in the photos, so please check them before purchasing. The rubber soles have hardened somewhat, but they still grip when rubbed against the floor, so they should be fine for everyday wear. Since it's old, I can't guarantee against tears or other damage. I bought it used and have just been displaying it. For display as part of a collection, etc.
