That is not enough information, at least for me. As carefully as you
can, measure the diameter of the charge holes in the cylinder, and
also of the barrel. Also, if you have any 32 or 38 caliber shell casings
lying around, try seeing what fits.
What part of the gun did this serial number come from ? Was it on the
butt, or on the lower part of the front grip strap ? Working in the dark
like this, we have to know where these numbers are coming from.
