Thanks for sharing, what struck me was how labour intensive it all was.
No worries.
For what it's worth, AVIA 46/116 says the Mossie required 30,000 man-hours to build, the Lancaster 84,000. (The document was put together in September '43, no doubt both aircraft required fewer hours by war's end).
Not sure how one relates man-hours to aircraft size, or volume, or weight, or indeed expected tons of bombs delivered before the aircraft was lost. There must be some kind of standard calculation.
Edit, had a quick look at the empty weights of the Mossie XVI and the Lanc I on wiki - empty weight on the Lanc was 36.5k, on the Mossie 14.3k (again, it's wiki, your Lanc may vary). So, it took 2.8 times as many hours to build an aircraft which was 2.6 times heavier.
I suppose it was all labour-intensive back then.
