Quote from: unbeldi on February 23, 2017, 09:04:31 AMI am sorry, now I see that my question about codes was already answered previously. I was surprised to find it already in my database.It is the only type 5002 that I have recorded.
Quote from: unbeldi on February 23, 2017, 09:04:31 AMIt seems the only phones that have that INSP(ection) marking are always those from Brockville.Am I correct in finding that whenever the INSP stamp is present, the third code group, in this case OO, does NOT have a digit associated ? I am sure I have not recorded all INSP markings, but this is what I recall from memory, and the only ones that I do have recorded, show so.

Quote from: unbeldi on February 23, 2017, 09:04:31 AMI believe they used the same stamps for "0" and "O", or the stamping tool used the same type. It is always impossible, IMHO, to distinguish them in these codes. I think we have to decide by position. This code group is always letters, and the digit if present is either suffixed (usually) or prefixed (rarely).PS: Unfortunately, this does not make it any easier in deciding whether the straight-line ringer indication uses a zero or an O character. The 1934 catalog seems to indicate it was a capital O, but I believe there are other examples where it seems to be a zero even in print.
Quote from: unbeldi on February 23, 2017, 09:52:40 AMBy the pictures, I would argue for calling the base Mahogany, and the housing Walnut.I think this makes the most sense, in light of the official description by AE:Mahogany: reddish brown, grained in black in simulation of highly polished mahogany.Walnut: brown, with black grain closely resembling polished dark walnut.
Quote from: AE_Collector on February 23, 2017, 11:42:42 AMI don't think I have noted the official description by AE before. Is that from one if the 4055 sales catalogs? It does agree very close to 100% with how I have clumsily attempted to describe my take of how the two colors should compare with each other. Thanks for posting that. In my mind that is a step closer to figuring out which is which once we manage to nail down a pattern to the A and B codes. I was afraid that we would eventually see a pattern where A color coded sets appear to be the reddish brown pattern and B color coded sets the brown black pattern but we still wouldn't be able to tie the "names" Mahogany and Walnut to the correct color code. That statement by AE makes it pretty obvious in my mind. Terry
Quote from: AE_Collector on February 23, 2017, 11:31:22 AMI have noted that all phones that have the P before the L (or N) indicate a Canadian made phone and in those instances there is never the final digit in the Third Group.
QuoteThis leads me to believe that that final digit somehow indicates something about where the phone was made and since the P at the very beginning indicates it is a Canadian made phone, the final digit isn't required on those phones. This phone doesn't have the P though it is clearly stamped Phillips Electrical Works Brockville Ontario in vermillion ink inside the cover. I will post a picture of the stamp later. There definitely are 40/50 models with the P as well as 41/51 models.
Quote from: unbeldi on February 23, 2017, 05:49:47 PMThe frequency of distribution of the trailing digits in the third group makes it hard to attribute it to different locations, if ''location'' means a different plant. There seem to be a lot more codes than plants that AE ever documented. Perhaps it means an assembly line no., #7 being the one that was running most of the time to produce Type 40 telephones. #7 shows up never actually for wall phones. The issue of assembly lines may have never been relevant in Brockville for some reason, or they used different QA methods. The INSP markings seem to have large numbers always, perhaps each inspector had a unique number.
Quote from: unbeldi on February 23, 2017, 05:49:47 PMI do consider the question about P as settled that those telephones came from Brockville, but we still don't know what it designates. Perhaps it is a marking requested by a customer. It is conceivable that a large customer such as General Telephone would order sets from both Chicago and Brockville, since they had operations in both countries. The catalogs specify to place orders to the two sales offices depending on shipping destination.
