Vintage Lisle Jeepers Special Creeper Wooden Auto Mechanics Model SP 2024 Nylon Rollers Clarinda Iowa

2024 I have not ever seen this model before - S P.
It measures 36 x 15-3/4 inches.
This is in solid condition - all the screws are snug and the 4 rollers all turn and rotate as they should.
The head rest is not cracked or truly even solid - it is a black color.
Write with any questions.
