Yep, that’s it!  I thought I had photo’d the other side..  I saw it in a small shop and should have taken more pics.  I may have to go back and take another look.

 

Do you think the number ending in 74 denotes 1974?  Or is that a part number.  Do you know when they were last made?

 

Thanks

It’s not a clacker (M57) it is a M40 circuit tester. Used for testing the circuit continuity in the set up from M57 to blasting cap. Yours was made in May 74.  Hope this helps.
