Need help with Swan 350

Hello All,
I picked up a really nice working Swan 350 at a hamfest this past
weekend. I bought it for nostalgic reasons as it was the kind of rig
my dad bought for me in 1965. I need info on how to fix the infamous
"Swan drift problem". Anyone have any websites I can go to get mods
for this rig including the drift fix?
Any help will be appreciated!

Ah yes the famous 3-drifty. I wonder if they had a temp compensation
adjustment. Consists of one positive and one negative coeficient fixed
cap of the same value, each one tied to one side of a differencial
trimmer cap, the other side of each cap tied to the tuned circuit.
You then adjust the variable trimmer for the least drift.
