Years ago during the Lefora years of the Forum we ran into several different models just like this rare 39A with some out of timeline crimped axles on them. They initially baffled some of us long time Lesney Regular Wheel collectors, so we began a Forum discussion about them. Because Nick Jones had become very familiar with early Lesney factory processes from conversations both with his own relatives and with a lot of former factory workers he had met over the years , his answer to our question was quite simple. In the event of a power or machine failure at the factory, the old style axle crimping machines were still available to finish any base assemblies that may have been on the line that day. Nick had pointed out that power outages were quite common back in those early years, (1961 or 1962 in this case) so old techniques to keep production moving and workers busy had to be used once in a while. This 39A's base could have been finished on one of those days, AND, there should be more to be found now that Ethan has shared his model's details with us.
This 39A is a beauty that most of us here would not have recognized as "Special" in any way, Great spot Ethan! When we focus on any particular Lesney casting for our collections, we sometimes begin to notice variants in colour and castings that have gone undocumented for decades. Thanks for showing us this one Ethan, I hope we can one day add it to Nick's codes and be able to note its discovery by you after all these years in "Hiding".

Cheers!, Dick
