2 missing desk drawer knobs (and 2 screws)

Hi,

My wooden desk is by the Lexington brand. The desk's part number is 225-534. 850712 is the serial number I think. It was purchased in the mid to late 90's.

I am missing the small knob for the top pull-out tray. It should be no more than 28" mm wide. The screw is about 3mm wide, about 5.5mm long.

I am missing one of the 2 larger knobs. The knob is about 49mm wide. The screw hole is about 4.5 mm wide. The knob is about 39mm long. The desk drawer that they stick into is about 17mm wide (the screw comes out the other end, but just barely.)

I am missing the 2 screws for the larger knobs.

I've attached photos of the big knob, the desk, and of a matching piece of furniture with the big knobs on them.

Thank you!
