Help identifying uPVC profile

[Hajj]

Hello,

I am missing some beading on my uPVC door. I would like to identify the manufacturer. The writing on the door profile says:

BS7413:1991 H.W.P. 16/01/04 20:08 M/C [37] 070205​

I do not know what the parts I have underlined mean.

I have also included some pictures below.

Thank you,

Hajj

Its 'Heywood Williams Plastics' profile, it was extruded on the 16/01/04 at 20:08, a lot of water has passed since then, HWP went bust, was bought, was sold, was bought again so god knows where they are in terms of extruding PVC right now never mind still extruding an 11 year old design, you could try here though with those photos

• Heywood Williams Plastics
• Dorchester House
• Wimblestraw Road
• BERINSFIELD
• Oxfordshire
• OX10 7LZ

Lol, I've been around the block a bit when it comes to PVC, seen most systems, repaired as many as well. The first part in 1991 was probably when it was BS certified and the last part is most likely the shift or production line it was extruded on
