Three NJ Precancel Items

Just found another packet of NJ precancels and in the process of going through them I found these three that I need help identifying:



1. I can find no listing for a double line precancel "Boundbrook, NJ". Could this be an L-1E?

2. The middle example from "East Orange, NJ" is printed in purple. Is this a common variety? I seem to recall that some precancels in colored inks command a small premium, but not sure if it applies to this example.

3. Would the third example from "New Brunswick, NJ" be classified as a Type 210 precancel?

Any help will be appreciated. Thanks.

(1) yes L-1E (2) yes, common no extra value (3) yes PSS-210

Thanks again for all the help. Glad to have confirmation that at least I'm making a good effort to correctly ID these precancel types.
