Values are a slight trick because the ladysmith is a non-factory refinish, and the grips on the (early w/grooved hammer and otherwise dang perfect) 1917 were refinished poorly (note how they no longer fit right).
Ladysmiths are anything in the 600 - stratosphere in price. If we are talking pure "replacement cost" for insurance, I'd say that's about a 800-900 dollar gun, assuming its all functional and the barrel isnt cracked from shooting .22lr out of it.
The 1917, despite the grips (which I would want to find replacements for) is about $1000-$1200 these days, they are very desirable, and thats a super nice one from what I see there. Could be hard to sell with the bad grips though.
