Diameter just in front of rim .470? Case length 1.3? Bottleneck case, no neck diameter
given. If the neck is in the .415-.420 range and the rim is .525ish--- 38 WCF (38-40)

FWIW--that long taper from case body to neck and a relatively short
straight neck section is typical of fired 38-40. The straight neck is much
longer on loaded ammo.
