If Dr Jones wore a kilt?

[OC Richard]

I give you Kiltiana Jones.

Yes for Junior!

But I was wondering about Senior. He's a Scot. What outfit would he have put together, in the 1930s, if he were to wear kilts?

Actually even for Junior, the original trilogy was set in the 1930s, and Weathered Tartans didn't appear until 1949. That sporran style didn't exist until around the turn of the 21st century, if I'm not mistaken.
