Re: Preparation of Construction Drawings
Gap Filler Radar Stations

Dear Sirs:

In order to facilitate the preparation of construction drawings, it has been decided that black line linen sepias printed off one of our lithographed sheets or one of your original sheets will be acceptable. Samples are being forwarded under separate cover.

If our lithographed sheet is used, your company's name should be placed immediately above the title block and the key plan, revision, symbol and building legend blocks added as required.

This method may be used for all drawings EXCEPT the 1' = 50', 200' and 1,000' or 1,320' plans, which are required on original linen or equal.

Yours truly,

(JW Alexander)
Group Captain
for Chief ofthe Air Staff
