I found a circuit for a 455 kHz BFO using an IF transformer, but it 
didn't work. I had to listen for a harmonic of the oscillator, which 
used a long brass screw to turn the slug, so at least it had enough 
range. The receiver was an ancient floor job (acquired for 75 cents at 
the Salvation Army), and only later did I figure out that the IF was 
probably 262 kHz or something else below 455. On my first QSO with my 
local Elmer, he was so strong, it's a good thing he had a little hum on 
his signal, because that's how I copied him. He was stronger than my 
BFO. Being crystal controlled wasn't all bad, as the tuning rate on that 
radio was pretty quick! I just left it parked near 3724 and waited for 
someone to call CQ. Compared to that thing, getting a Command Set was 
like inheriting an S Line.
