Long before I had an HP calculator I remember looking at an LCD model but lately out of curiosity I have tried to find reference to it but drawn a total blank. Now I wonder whether my memory is playing tricks.
I do not know the exact date but it was definitely before 1974. The display was either tilted or was tilt-able, the characters were fairly big, maybe 15 to 20mm although low contrast and I am pretty sure it was manufactured by Siemens.
Does anyone know what it might have been?

Maybe a Lloyds Accumatic 100?

Hi.
Interesting... According to this site (I see you actually point to their picture) it had a filament lamp to provide backlight illumination. The LCD's low power feature seemed not to be the key, for they used a filament lamp to illuminate it.
Anyway, it was the first one. Looks pretty nice, though.

Wasn't really reliable. These guys dropped the technology in 1972 in favor of LED's. Cheers, Joerg

The calculator I played with was certainly about the size of the Lloyd one, but the display did not have a backlight and I'm sure I would have remembered the weight of four D cells. I am still positive that there was a German connection and I can still see 'Siemens' in my distant memory.
Oh well. I'll keep looking.
Thanks
Ian

Siemens???
There was a Sears Desktop out but I remember it was identical with the above pictured "Rockwell" model.

very likely "Sears" and not "Siemens" - Siemens never built any calculators (actually neitehr did Sears - as Joerg said, the LCD desktop is a Lloyds OEM. Btw. Rockwell did not sell these under their Rockwell brand, they only did OEM. From the same timeframe there is a pocket calculator very much like the Minimath LCD, called Lloyds Accumatic 40, also available from other brands...)
Another possibility would be a Rapid Data Rapidman 1208LC (another Rockwell OEM). These were a bit later then the Llyods 100.
