Mosquito Prototypes W4050 etc

[Larry]

Apparently the first prototype W4050 was dismantled and taken to Hatfield for its fist flight, but I understand that W4051 and W4052 were flown out of a nearby field adjacent to Salisbury Hall.

How many of the W4050-W4099 batch were built at Salisbury Hall. I guess they stopped at prototypes rather than any production aircraft at Salisbury Hall?

Also I understand that W4050 actually has the fuselage on W4051, as W4050 was cracked beyond repair when the talewheel broke sometime during its testing days.

Sadly I can't find confirmation.
