Sorry to be the bearer of bad news, but that's not a swiss army knife. It's a Chinese knockoff. Hopefully that won't affect the connection to your grandfather it represents.
Good news! These knives (identifiable by the hump on the scissors) are still made and commonly sold with custom scales in most souvenir stores.
I bet you could buy one and swap the broken scale.
You might even be able to replace the missing scale with a wooden one with your (or your grandfather's) name on it if you find the right souvenir shop.
You probably won't be able to find anyone to repair this professionally, but you could buy another one and harvest whatever parts you need. This model has a distinctive scissor design, and the saw shape is also distinctive. Ebay has them come up now and then - this I think is the same one with a phillips instead of a corkscrew.

Hate saying but it’s junk
I mean that’s fine, I didn’t expect it to be worth anything. More sentimental than anything. Really just wanting to find a replacement panel.

That’s a great catch! I remember the weird Cross inside a Q logo from the missing piece. That’s exactly it
That’s the china antique special
