This grouping is thus mostly to do with Queensland manufacturing. ā

Gatic is illustrated by rectangular and round covers.
The rectangular models are similar with some minor differences: #736 is the basic model 280 x 180mm. #925 is missing an identity plate. #1579 and #805 are marked MCC - Melbourne City Council. PG refers to Parks & Gardens department. R - Recreation.
Gatic round covers - #761 has recessed opposite side of IāD. #1541 doe not.
Only one square cover - #1935, 90mm square. ā
R&S Grating represented by square and round covers. 4 square models are illustrated. All with recessed ID except #826 which is raised. Possibly the oldest. #153 marking Ductile is possibly the next oldest. #157 has no 'W'. Note excessive wear in that area.
Round R&S covers - the difference mainly being the ID in recessed slot (#202) versus recessed writing (#1043).
Crevet 199 (#579) is the only example this popular model from the three manufacturers. 199 can exist as S199 also. the Crevet model is a modern cover with a round cover and casing. More common to see this model as round cover with square casing. Still with the same number of raised lugs.
