elevation screw for a civil war cannon ?????

[FinderKeeper]

OK , I give up on this one , is this a elevation screw to adjust a cannon for distance . Found at a civil war site. It is 15" long

I hope it's an "elevation screw to adjust a cannon for distance".

But it looks more likely to be a relatively modern wall anchor bolt & mount plate.
I'm basing this on what looks to be a modern hex bolt under the flat metal plate.

Does appear to be an anchor of sorts. An elevator screw would have a very coarse "acme" type thread.

Tony_in-SC is correct. As he said... "An elevator screw [for a cannon barrel] would have a very coarse "acme" type thread." If you care enough to want verification of what I'm telling you, do a google-search for images of civil war (and earlier) cannon carriages.
