Having compared the drawings for Suzanne with what I have seen of Dora's they look remarkably similar, except that there are 21 sheets in the Suzanne drawings and only 16 in the Dora set
I suspect that Willy originally drew up this engine and sold the rights to a number of ME suppliers across Europe.
I am hoping that GLR may, as a result of my enquiries, be able to provide this engine again in the future and that will be at UK rather than Swiss prices
Willy has also designed some other rather nice engines
