Certainly worth a crack. I've spent more on less I am sure. A 20 E could be a spectacular piece. Fwiw I have owned 7 Lefever arms 20 ga guns and 6 of the 7 had "bad barrels." 4 with barrel walls .010 to .018, one with a hairline crack and one with bulges. 4 were fluid and 2 were Damascus. The 7th I have yet to measure as it sits in the safe likely unfired and I am not sure I want to know.
( I am clearly a sucker for a Lefever )
Mark interesting post ,I too am badly stricken with Lefeveritus but up here in Canada they are beyond rare ...you mention that you've found six with bad barrels ,did they come from the factory with thinner tubes or were they tampered with through the years ...I ask because most I find (which are few ) seem to have above average wall thickness with the exception of one F grade that is on the thin side
