Gauge of Page's strings..

[PajLvr@xxxxxxx]

Can anyone tell me what gauge/ Brand of string Page used during the days of 
Zep(if that is to vague or to broad of a spectrum...how about one song, show 
etc..) I would imagine a heavy gauge for tone but....how heavy??? I have used 
various gauges and brands(current gauge 11), while tuning down ...and 
adjusting my amp and controls on my Paul. However, have not come across the 
"exact" sound I am looking for...(and don't ask what sound I am looking 
for...just a heavy crunch right now)BTW...the person who asked for the tab to 
Midnight Moonlight/Swan Song...did you ever get any replies?

Thanks,
Von
