When I was interested in Speed Graphic I found a lot of information
originating in the US by searching on the internet and if you do this you
will get almost all the history and models. Incidentally a focal plane
shutter model is used on Time (i.e. open) when you fit a lens having a
shutter.... provided the focal plane shutter works on time and say 1/10 and
1/100 reliably you could use lenses with no shutters or enlarger lenses as
well. I mean you don't need the highest speeds as you can stop the lens down
to f22 or use a neutral density filter or a polariser to absorb strong
sunlight. In theory you can use f64 and cover/uncover the lens with your hat
so who needs a shutter anyway?  It's worth experimenting if you can borrow
lenses.Philip

The Focal plane shutter issue made me think about Century Graphic 2x3
or 2 1/4 ... - it would allow shorter lenses and propably the shutter
in the 2x3 Speed would be irrepairable or only with major effort
anyway, so I might just as well get a Century, or no? Was there any
other difference?  There were a few different models.

    I was thinking about it as a mechanist I know build a 6x12 back
    himself, for sale but he later kept it himself, and from what I
    know about him it was even more accurate (dimensions - film plane
    distance to GG?) than several originals that he measured :) But I
    don't know yet the cost of it, though.


Thanks a lot!
