What about his legacy? Well, his name and magazine articles are known amongst some older model railroaders. He's known fondly amongst a few, but others associate his name with low quality work in balsa. Hopefully if you're a long time reader here you'll be aware that although there were indeed some questionable projects, the majority of his work was of good quality, with maybe a half-dozen or so reaching into the craftsman category. I think the photographic technology of his era did many of his projects an injustice, as it did with the work of many other builders.
The plastic kits he had some involvement with appear to be all out-of-production now, although a few of the kits were manufactured for 50 or so years under one brand name or another. There is healthy buying and selling of the old kits online, although it's generally not known he designed them. There are a few exceptions like the AHM kits that credit him in a red box-top label. It's a shame that he or his estate didn't profit financially from the popularity of these products, although I suspect the amounts of money involved would be small.
His plastic kits were in the cheap-and-cheerful end of the spectrum when they first hit the market. But, these days it's not unusual for them to get harsh reviews on auction sites - not to mention be misdescribed - and if built unskillfully straight from the box, they can look crude. But, as with all kits, a bit of care and creativity can yield a decent and interesting model.
The plastic kits constitute a sort of invisible history. Throughout the '70s and '80s they appeared in numerous magazine photos, and as basic components in many kitbashing articles, but in most cases their origin remained unknown. They formed a sort of background music to the model railroading vibe of those decades. Many of the kits are still seen on layouts today, and even in the odd magazine article or two. Again, their appearance in articles, layouts, and at auction sites is an almost silent Moorian melody still playing through model railroading.
And he's credited with influencing the design of a few laser-cut craftsman-style kits. I've found a couple online, there might be more out there. Time will tell.
Overall, I'd say his legacy is somewhat modest, and a bit on the invisible side, compared to that of say John Allen or John Ahern.
An aspect of his legacy that seems completely lost is his approach to modelling and writing that I touched on in The Moore Way. This aspect isn't alive in the kits simply because they're mass produced consumer products. And, ironically enough, Mr. Moore hated to build kits, so you can see why it's odd that the most enduring part of this legacy, kits, are things he himself hated building.
