RE GOSHAWK II.

With reference to your BY/C6/H26-1-21, we have not yet received approval of the bonnet and radiator from Mr Royce, but as the dimensions given are his own, and the model it is intended to make will be easily altered and will probably require alteration during the process of matching up to the body, we think it would be quite safe to proceed with the model on the lines of "N" Scheme 709 and "N" Scheme 710, of which we send two prints herewith.
Since these two schemes were made, however, the frame has been considerably altered, and we should be much obliged if you could modify these two schemes so as to agree with Lec.1338, keeping the top of the bonnet and radiator the same height from the ground as originally, that is to say, both the radiator and bonnet will be somewhat shortened in height. If you could do this we should re-submit the scheme to Mr Royce and we think you might proceed to make a model straight away. It will be understood, of course, that the frame model is to be like Lec.1338.
Mr Spinney is very anxious to have a date of probable delivery for this model frame, bonnet, radiator etc.,
Could you give me an idea of it?
