An obscure, but nice plane! Hannants list a future release of a 1/48 scale kit by the company "Karaya" on their catalogue website:
http://www.hannants.co.uk/product/KY481004Karaya is a Polish kit firm, who seem to do multi-media and resin model kits. I cannot comment if this kit will be resin (the listings at Jadar seem to show that Karaya mainly do resin, but Hannants list it as Injection Plastic), and if it isn't an IP kit, then I would be careful.

Apart from that, there's also a 1/72 kit from Pegasus:
http://www.hannants.co.uk/product/PEG4015Would be good as an in-flight model, but since your other planes are all 1/48 to 1/60, might be a bit on the small side for ground use and next to the rest of your flying corps, I'm afraid.
