Could anyone help me identify this Pagoda hardtop? It was on a 1983 Pagoda Euro 280sl but doesn't actually fit (doesn't seal and was forced on by the previous owner).

Wording and numbering on the back side windows:
SEKURIT
ESG-H
43R - 001025
DOT27 M 52 AS2
ESG WD

The back window has printed:
SEKURIT
BERBUND
43R - 001060
DOT 27/M75.5/ AS2
THERMOVIT
VSC(*) WD

(*)I think it's a C

Perhaps these identifiers are actually just for the windshields, and if so, is there a part number posted somewhere I'm not seeing?

Thank you in advance )
