I think there were several different Lincoln (perhaps Lancaster too?) engine test beds with 5 engines, one example was Lincoln RF530 with a Napier Naiad in the nose, displayed at the 1948 SBAC Show.

Thanks for sharing this wonderful and unique set of pictures, Jochen.

Oops, sorry, it’s the Hart with a Mercury engine – I was too busy looking at the swastika! Four of these aircraft were “lent” to Finland during the winter war. The photo is still attributed to Mike J however!

I would have to disagree, Mark12. An ammeter shows charge or discharge in amperes, not volts, so the markings are more likely to be from -20 amps to +20 amps, with zero in the centre. Normal charge would register some amps positive (showing that the generator or alternator is working), discharge would be some amps negative, in which case your batteries will soon go flat! The voltage (24, 12 or any other direct current value) is immaterial in this case!

Rebecca’s Song
J.M. Kinkade III ©1983-2002

Ain’t nothing set in stone baby
I love you the way that I do
Nothings set in stone baby
Love you the way that I do
What ever you want
I’ll be there you

You got something baby
I can’t stand to see you go
You got something baby
Just can’t stand to see you go
God knows I love you
Don’t leave me all alone

Down home in Texas baby
That’s a real fine place to go
Down in Austin Texas
That’s a real fine place to go
That’s where Stevie
He come from

You know I’m guna miss you baby
Until you come home
You know I’m going to miss you baby
Until you come home
My love for you is as deep
As the day is long

Woah now Rebecca
I want you to know this is your song
Woah now Rebecca
I want you to know this is your song
I’ll keep on loving you
Even from afar

The planets travel around the sun baby
Don’t you know that’s true
Planets travel around the sun
Don’t you know that’s true
Just like my love for you
They keep me warm

I had the full works, even at the small provincial airport at Green Bay, Wisconsin, and the metal detector found the stainless steel wire holding my ribs together! I am very impressed with the sensitivity of that machine!
However the checks in and out of the USA meant arriving 3 hours early at the airport to check in, and whilst I agree totally with having security precautions, I felt that they were a bit over the top compared with my experience in Europe. I thought that the USA was running profiles on suspect passengers. They applied the same strict checks to everyone however on the flights I took. In several cases the check-in took far longer than the actual flight!
