Dear Sir,

In further reply to your letter of the 19th inst., concerning U3. Osram Rectifying Valves we sent a copy of your letter to our Head Office and this morning we received their reply, the gist of which is as follows:-

Any modification of this valve is entirely out of the question as the U.3. is an obsolete type and was originally made for certain Government Depts. As what is known as a short life Valve U.3. had never been on any occasion put out as other than this, and there is now no call for the type, so that it has ceased to be manufactured.
If however you would give us your exact specification and requirements, perhaps there might be some other type of valve which would suit your purpose.

Concerning your first question we certainly think that our Works will have still some U3. Valves in stock, but we are obtaining their confirmation on this point.

Yours faithfully,
AND ON BEHALF OF THE GENERAL ELECTRIC CO LTD
...Branch Manager
