Bill, Re: Your WRA sight. The aperature is probably WRA, but you would need to look closely on the side of the gear rack at the bottom near where the teeth end. It could be BMB or BMR and if so, those letters would be lightly stamped in that location. Otherwise the WRA and BMB (R) aperatures were the same shape. The sight cover is the typical SA cover with the wide verticle ribs. Can't tell what the body is by your pics and you would need to take the sight off to determine if it is a WRA body. The pinion and knobs are the T105E post war type.
