Elgin factory was setup by a few Waltham guys. Elgin's production volume is bigger. One ebayer listed an Elgin starting at $0.99, free shipping, no reserve. Surprisingly, no one bid on it.

It's one big dollar, shipping included!! How could seller not losing money if someone had put down $1 on it.....
