Hi Guys

Geoff is asking a very good question. To list all sources are pointless, since all I can see from very detailed three view drawings are very minute differences. I doubt any of those are visible on a normal photo. I would say it is more or less impossible to see any difference unless the photographer has made a note on the back... OR the interpreter makes an educated guess, that is knows the date of the photo and the unit(s) pictured!

So if you want to convince me you better come up with something better than almost non visible differences in various drawings.

Cheers
Stig
