The engine shown in post #1 is a late ferrous 'Russkie Mills'. It is a really nice example. It is the same as the Russian Doonside but is not a real "Doonside" as it was not sold by or with approval of Ivor F. I bought it direct from Ilya Leydman who at one time imported a range of Russian engines into Australia and sold them under the business name "Macheast Trading".
