Swift Grand Prix 1 8x40 (1 Viewer)

Hi
New to this forum and to birdwatching, so any help would be appreciated. I have two pairs of old, but excellent condition binoculars, which I am giving to my wife and daughter. The first pair are Carl Zeiss Zena 8x30 and were made in DDR in 1960's. The other pair are Swift Porro Grand Prix 8x40. Both pairs have served me well over many years and I have had no complaints as to their quality.

Can anyone tell me anything about the Swifts, as thet were kindly given to me by a friend who sadly is no longer with us.

The Grand Prix range are a budget binocular from what I remember. Good for bird spotting with quite bright images. Probably not up to the optics of your early Jennas though. I use mine very rarely as I own over 30 other pairs!
