Mellotronists

I saw Frothingham's unit when he lived in Eugene, OR back around 
1993...a single wide mobile home up a steep road just west of town 
packed with vintage keyboard instruments. You had to goosestep over 
all these things along with his extensive record collection. 
Which 'tron he used in the local band Marble Orchard, I dunno, but 
the Mk. 2 looked cosmetically okay even though one half of the 
keyboard didn't work at that time.
