I don't remember this episode. Why did the family decide to sell Lurch's harpisicord, and how do they get it back?

I have not seen that episode in many years. I think they make the harpsicord as a donation to a museum. They do not realize how much it means to Lurch. I don't remember how they get it back for him.

Here is the description from TV.com:

Lurch and His Harpsichord
First aired: 3/19/1965 Production Code: 7000-25

Lurch' s harpsichord turns out to be a rare survivor of an extinct make, so Gomez is persuaded to donate it to the local museum. Lurch is left inconsolable, so the Family attempts to get him interested in other pursuits, like drums and needlepoint to no avail. Finally, Gomez and Fester make the ultimate sacrifice -they build Lurch a replacement.
