So fun fact - I was part of the team that created these kits. I actually named the company!
David Gormley in Derby was/is the owner of RGMUK. Myself and a few others in the US did research, drawing development, etc., and then David would do the final CAD and contract the laser cutter there in the UK. The reality is, the laser cutters we used have all gone up in price.
Seriously up. David and I still build our own cars... and occasionally he does very small runs/reruns for friends - but if you thought the prices were high before... well, we're not stupid - we looked at several options. There is a reason the kits are no longer offered.
Given my frequent travels between the US/UK, I would mule in cases full of AMS bodies I'd buy for cheap in the US, and then he would use for builds there. Additionally, I brokered the deal between RGMUK and Jonathan Bliese at EMW in California to "import" the RGMUK kits. Sadly, the demand just wasn't there. In the late 2000's and very early 2010's, wood was cheap, laser time was cheap, Phil Dipple was running large batches of NBW's from a Chinese vendor custom made for him, and AMS cars were readily available. All of that is gone.
Honestly - I was the *
kid* modeling 1:20.3 in my 30's... and everyone I met or worked with in CA and at the national shows were 55+... sadly in the past 10 years, many of the guys have passed on. Those that have not, have sold off their collections and moved to retirement homes. David and I competed to see whom could have the "second largest MOW collection" behind Dean Lowe. Dean's since moved to a small condo with no room for trains. Jonathan moved, and closed EMW. David Crocker passed. Don Winter passed. Phil Dipple moved and put PNG in mothballs. Greg Posta gave up traveling to shows. The Big Train Show was moved, then sold, then became an "all scale" show, and then finally shut down. Durango Dan's 1:20.me shutdown. Dave Goodson stopped taking new conversion work.
Moreover, H. Lee Reily passed at Bachmann, and with him the passion for 1:20.3 cars. Kader's purchase then killed it. Rich Yoder stopped almost all new products. Bing at Accucraft/AMS has contracted, and sadly Fred Devine passed. BACK2BAY6 in Telford closed after the owner passed (who commissioned many of the RGMUK cars for sale in the UK market).
There was a great group of a dozen or more folks that kept 1:20.3 relevant. Two large manufacturers, and a half dozen "cottage industry" kit makers, all using the same folks to research and develop new cars/kits/offerings. Moreover there were 30-40 folks in the western US and Colorado/Texas that manufacturers knew would pre-order
anything new for the D&RGW. Given the limited numbers needed for runs at Accucraft and RY (as low as 50 pcs, typically 100-200 pcs at most), making a new car wasn't too much of a gamble. Now, less than 10 of them are still active that I know of.
Very long post, short: RGMUK didn't simply stop, the economics and the market changed. We still talk about running new kits from time to time (typically each trip I'm over, after a good evening at the pub), but each time we run the numbers, it just doesn't pencil out.
If you're still looking for kits - the GAL line is an option. They basically picked up and ran away with David's model for laser cut "add on" car sides for AMS cars. Honestly once they started selling in the US, RGMUK couldn't compete due to TATL shipping costs. Worse yet, each time David would release a new car, it would magically appear on their site a few weeks/months later. You can also try emailing David... there are still a few cars in various states of finish. One example I know of - last year he did a few "chicken coop" MOW diners for a client.
Anyway - hopefully that sheds some light on it all... glad you like the kits. I miss them too. There are lots of factors out there as to why they were discontinued, but simply not trying a "new way" of making them is not one of them.
