"The two pictures above show the difference between early and late parts. The center bar on late MGA production was strengthened by adding extra metal where it meets the outer rim. I own two MGAs - one produced in August 1961 (102721) with the early style and the second in April 1962 (108477) with the later style".

This is the rear view of an original part. Note that both early and late style parts had "DH" cast into the rear side. Reproduction parts do not have this feature.

Apparently they are still in business in Bradford, Yorkshire, UK:

"My original cowl vents on my MGA 1500 1958 (Chassis no. HDR33/36743, body no. 47166) have a different marking on the backside (see photos). The vents were on my MGA when I bought it in 1972. Original? Who knows".



Now I am getting lots of reports of early car having the 7100583 vents, so they appear to be original issue for early production. Now a new challenge, trying to fill in the gaps to identify the change point from "7100583" style to "DH early, and from "DH" early to "DH" late style. Only for the concours buffs of course, but if you think your vents are original issue, and you have the opportunity look, let me know which stye you have and the car's chassis number.
