I wonder whether he gets any replies

I wonder how much the tooling was in the day when Austin produced this model?

I realise this does not cover tooling for mass production, but the cost of building the three prototypes was £1,672. 19 shillings, or approximately ten times the retail value of the production car.

Roughly £90,000 today. I suppose much of this would have been done in-house - pattern making and casting castings included if the foundry and forge were operating by 1922.
