Don't think I've ever heard if this plane let alone seen a model.

Ok here is a series of pix I found on t'interweb
http://www.bing.com/images/search?q=boulto...l%2Fballiol.jpgStrewth that's a long URL (how do you contract this into 'Linky'?!)
Anyhoo..........this shows the two fuselages retrieved from a scrappy in Failsworth Lancashire in the 70's. BPA are essentially building metal clad wooden frames around them to make static external replicas.
The cockpit shots are the best I have ever seen anywhere (Pilot notes are grainy b/w anyway) and since they are being refurbed by PB oltdimers would be inclined to believe what I see.
For an overview of the Balliol see here (even this uses the c****y Aviation News plans - c.f. the canopy and 'notched' curve from windscreen to spinner again)
http://en.wikipedia.org/wiki/Boulton_Paul_BalliolNote that it flew with a Mercury Radial (prototype), AW Mamba (T.1) and then the RAF got cold feet and decided to use surplus Merlins (T.2). Do some digging around and you will find interesting variations on the airframe (nose - obviously; tail assembly and the canopy as well). There were also minor detail differences. For an obscure 'nearly was', the Balliol offers some interesting diversions. Unfortunately from a colour scheme point of view you only get anodized metal, natural metal, high speed silver (with either yellow trianer bands or dayglo details) or one overall red pre production example used by PB (G-ANSF). As an aside, many examples flew straight to an M.U. and were scrapped in situ. Drifting further off the main point, Blackburn built a batch and curiously cowl panels were not interchangeable with BP built examples. Final ramble - all had manual wing folding.
I know that I have banged on about the Balliol, but this is perfect resin fodder and even I would be tempted by a CMK resin even at their prices. If the better half moans, I would say that it was only the price of a perm!!!
As for real airframes, there is one T.21 at Cosford (this should really be with the FAA Museum!). There is definitely one complete example in Ceylon - apparently the Shuttleworth Collection tried and failed to get it to add to their trainer collection. Rumour has it that there is another substantially complete airframe out there too. Other than that, all you have are the two semi replicas with the Boulton Paul Association in the Midlands. These guys did something similar with a Defiant too - v. nice!
Hope this helps and if anyone reads this, please take time out to have a look about the real thing.
