Group, I got a few buildings that I noticed that have printing under them, someplace others of the SAME thing, don't! For instance I got 2 of these:

This one has the roof printed on! Or well molded on wording, that says it was made by Plasticville on June 17, 1952, along with the patent numbers.... see:

NOW on other buildings made by Bachmann Plasticville, that are newer don't have this! I know what it means in the molding process, the original mold had it added to it, and then a new mold was made with out the added in date to be on the inside of that mold....BUT, my question is, back on the one withthe dates, did they change the date EVERY time they did it on a different day or did they use the same mold over and over for years and never change it and that would mean that the molding would be original to that date but it could be as old as 10 or 15 years, or even till the mold wore enough that warrented them to make a new one that probably didn't have the dates in them?
Make sense?

My guess is the date refers to the date of patent, not the date of manufacture. Here is a reference to the patent:

Thomas, I had thought this is what it was....As if it would have been the date of manufacture, it be a costly feat, all the time in man-hours, and the re-making of the mold and the left over old mold that would be costly!
I just had to ask!

There used to be a method call Heat Stamping, it used an electric heating element, and it would heat up metal letters put into a slide, and they could stamp labels or plastics with them, well I'm assuming plastic, too. So it wouldn't be impossible to date-stamp plastic bits, but it was probably more economical to ink stamp that than make an impression in plastic, or just stamp the box with the date of manufacture. Usually the only time the mold is changed is when it changes hands to another maker, who might update it some to reflect their own manufacturing of a copy or continuation of a product, like Life-Like did with Varney molds. Although they just ground down the impression to remove it, and didn't really add anything back.

Jerry, Yeah, heat stamping was sort of easy! I used to do it myself!
I have letter and numeral "stamps, that when placed on metal and then struck would add which ever you were using to the item pressed into....
WELL, back then, I found that if you made a holder, added in all the stamps you wanted to write out a word, and then heated them a bit and just lightly touched them to the plastic it would add that word! I had this set up but have somehow misplaced it in the multiple moves since that time. This was over 10 years ago or there abouts.

| You have to remember Bachmann has made those literally for like 60 years now and the tooling's surely undergone repairs and changes in all that time.

The molded-in date is the patent date. When manufacturers want to mold the date of manufacture into a plastic part, they generally incorporate date grids or date wheels into the molds. Date grids have rows labeled with the months of the year, and columns labeled with the years of expected manufacture (or vice versa). A punch is used to mark the grid box corresponding to the current month and year. Date wheels consist of a wheel with months, and a wheel with years of expected manufacture. They are turned with a screwdriver or similar tool to line up pointers with the current month and year. If the day of manufacture is needed, a date sticker, stamp, or handwritten date is used. Tooling is way too expensive to replace unless absolutely necessary.

Glenn and lvrr325, I kind of assumed this, but you know what happens when "one" assumes......
I know tooling is expensive but you never know, and I had to ask as I had to second guess myself on it.
