Developmental Western Electric Triode Planar Grid With Interlaced Filament

Description

Please be sure to review all my other auctions after you have looked at this one!  I will be listing a broad and diverse range of vintage communications and technology items, related books, periodicals and ephemera...  Something for everyone!
Here you are bidding on a scarce, Developmental Western Electric Triode Vacuum Tube With WE Lab Serial 65066.  It has a good filament!
I am guessing this is probably part of the Type P development which resulted in a small batch of VT3's for the Signal Corps and ultimately led to the Type N and the WE215...
Internal construction is unusual and excellent!  Press is marked "41711" and "106".  The anode is a box plate about 7/16" square while the grid is a 5 x 2 planar, ladder type structure with an interlaced filament.  I have only seen this interlaced type filament on one or two other early WE tubes!  I have tried to give you a view with the photos...  The WE Lab marking on the glass is clean and sharp.
I have tried to take good pictures to indicate the physical condition! Ask if you have any questions...
If you collect Western Electric vacuum tubes, this is a must for you!  It is quite extraordinary!
Shipping weight will be about 2 pounds.
I will pack all items properly and with great care.  I have been shipping these kind of vintage items worldwide since the late 1980's.  Buyers are responsible for shipping, insurance and material costs and any applicable duties.  I usually can ship within one business day after receipt of confirmed payment.
International customers are very welcome! Bid with confidence...international shipping is not an issue!
