4-1/2" diameter reel on a switch rod?
That's something you don't see every day.
Trying to find one in that diameter light enough to balance a switch rod could be a challenge. Orvis made a 4" diameter cassette style disc drag reel some years ago, and there are still some around used. Its called the Rocky Mountain Large Arbor model. I still have one, and that model would likely match up weight-wise on a rod like yours. The cassette spools are quite handy too.
Orvis also made the Battenkill in a large arbor style (fixed spool), around $100 used.
Both reels are less than 8 oz., both around 4" diameter.
For what its worth, on my 11'6" 5/6 baby spey rod I run a Hardy Zenith multiplier (3" X 1-1/2")--fast line pickup, but daintiness to match up with a lighter shorter rod.
Just because no one understands you doesn't mean you're an artist...
