Machine Shop '73

Martin noted that the machine shop that appeared as a new product in Pola's '72 catalogue, appeared in AHM's '73 catalogue. You can see that AHM used the same painting Pola did. I wonder if there was a '72 AHM catalogue, or if their '73 catalog was published late in '72 - say, in time for Christmas - because I'd like to narrow down the date when the kit became available in North America. Well, on the other hand, given where we are in the 21st century, it hardly matters much if it was released 47 or 48 or even 47.5 years ago, the fact that it's had the life and longevity that it did is amazing in and of itself.
