I purchased my 4x5 Norma new in 69 and it's marked M69 on both standards. There's also a 43 on the front and 45 on the back. There are no focus locks and the geared segment is nylon or similar.
I still have the receipt and ran across it some months ago. Seems like the cost was around $360 for the basic camera. Put that in an inflation calculator and see what it would be today. To put it in perspective I purchased my first used M2 Leica body in 68 and it was $250.
