The title pretty much says it all.
I've contacted RT and there is no current planned production of the model at this time. :(
It's a pity you missed the one that 009 Sales had a couple of months ago (albeit a Saltford Models one) - there was also a made-up RT Models one earlier this year.
Not very helpful, I know, but it shows they do very occasionally appear, so worth keeping an eye on the website.
