Hi John,
Welcome to the forum! I'm a local digger from RI too. It looks like you found a decent dump. The Berry Spring bottles are fairly common but look great. The Conley flask in uncommon, I almost bought one at a local show. I'm sure you'd love to find the bottle through the link below!
The Conley I saw for sale was around $30, but I know the seller prices his bottles on the high side. I saw one on ebay asking $5 and nobody bid on it (I missed it...). Probably $15-20.
That flask is a killer find...wonderfully sun colored I love the lavender hues from the pre-WWI era glass. I would deffinatly give you $15 bucks for it if your want to part with it..send me a pm and let me know [] . Welcome to the forum!
