Boston, Mass. Sta. No. 7

Has anyone ever seen this postmark before? It was applied to the reverse of a Registered Mail Cover from 1945. I've never heard of a "Sta. No. 7" in Boston (most were identified with letters rather than numbers back in the day as in "Sta. A"). I was wondering where this Station may have been located. Could it have been a special Station in place only during the war years?

There is a fire station No. 7 in Boston Mass. Could that be a clue perhaps?

Also, I don't know if this would be of any help or not but the original layout of that yard is just enormous, so it could be a passenger platform or some other part of the yard; perhaps an out-building or similar? just maybe it could even be an R.P.O. hand-stamp?
Anyway, Here is a map that illustrates what I mean. I couldn't find a thing on the inter-web but just this stuff. Sorry I couldn't be of more help.

I Love Stamps: What is the inter-web?

WT1: What is the address of the recipient of the letter? The station was probable in the general neighborhood of the address.

The General Post Office (GPO) located in the McCormick Court Building on the Milk Street, Congress Street block had numerous delivery codes, (01-10 now 02101- 02110+). The GPO also had multiple (largest in city of Boston) service counters. The Station 7 may relate to the service station the piece was received at when mailed.???

Just a corny word for internet Glenn.

Now that seems like helpful info eligies!

Both addresses (sender and receiver) were located in Boston. The postmark shown in the above example was dated the day before the other (which reads "Boston, Mass., Postal Station A") so I assume "Postal Station A" refers to the location where the cover was sent to.

On the other hand, the "Boston, Mass. Sta. No. 7" postmark was probably from the post office where the sender entered the item into the mail. The return address of the sender was a law office that had been located at "Cornhill, Boston". An internet check reveals that Cornhill no longer exists but is now part of Government Center, so I suspect the postmark may have involved a Post Office station once located in the old Scollay Square area:

Incidentally, I did pickup a couple of references in the Postal Bulletin (dated 1905 and 1906) suggesting that the Postmaster General ordered that post offices establish "numbered stations" for the transaction of money order and registry business. Since the postmark shown was on a registered mail cover, I suspect that perhaps Station No. 7 may have been the post office where the item was received for mailing.

That's the most I've come up with to date.

Boston is an excellent city for studying postal technology and postal history - especially machine cancels, zones, etc.

Here is a scan from page 243 of the July 1945 Postal Guide listing the Boston branches and stations. The unscanned 3rd column goes up to station 224, with quite a few missing numbers. Clearly too many stations for alphabet letters. (Many modest sized towns switched back and forth among letters, numbers, and names.)

Looking earlier, the 1907 Postal Guide lists 128 numbered stations in Boston, all of which were operating AND it give their addresses. Station 7 (then) was at Norfolk & Corbett Streets - no idea if they renumbered them or not, so this may not be correct for 1945.
