   You have one of the earliest Realists, before about 1950.

They are said to be sharper than the DW lenses, especially at the wider
apetures, but they are also said to cause more vignetting at narrow
apetures than DWs.

   Can't say for sure, but, IMO, if they are worse for vignetting that
the DW 3.5, then I'd have to assume no.
