that picture is very fuzzy..hard to make out the details..
does it have something to do with testing?
I'm wondering how big this thing is...
Is it closer in size to the pic, or to your avatar?
Or, is it bigger or smaller than both?
Is it some kinda key?
Is that a wire or a bar going thru it?
Simple conceptual testing was implied. Testing is a broad term that can be misinterpreted--let's just make this easier for you, and restate the answer to the query as...no, not used for testing.something to do with lasers?
rigging for the mirrors(or some other part) used in laser testing?
Not to confuse, the operation facility comprises both bar material and wiring.
Is the pitcher of it considered to be in the up-right position.???
is it an engineering tool?
yes.You mentioned wiring...Does it require power to operate?
Looks like a joiner of some description.
