Roger,
See if you can get a copy of "Revolution in the Sky". It's a wonderful book about the early single engine Lockheeds. The Air Express, Vega, Sirius, Altair, and Orion are all covered. There are lots of pictures and some color schemes given. I believe it's out of print, but copies keep showing up on ebay for very little money. Or you can do a search at www.abebooks.com for a used copy.

Also, get yourself a copy of the William Wylam scale drawings of the above mentioned aircraft series...they're something else. I think they are available from Model Airplane News. Incredible detail on the Sirius and the others.

I'm currently building a 123" 1/4 scale Lockheed Vega, from my own plans, which shares the same basic fuselage and wings with the Sirius, and the above mentioned book and drawings have been most useful.

The Lindberg Sirius is the only one left, so you aren't going to find a photo pack for any others I'm afraid.

If you want more info on the book, like the ISBN number, let me know and I'll look it up for you.

Good luck with the project! D

Cheers, Nigel
