Wrenn produced the well known W4325P "OXO" Vented Van in white with the OXO symbol painted in red on the white plastic body. These were produced during Periods 2 (Triang/Wrenn) and 3 (7.5p) by Wrenn, Basildon.

The most common is running number DE545533, and the rarer version is DE545523.

Even rarer is the plain white body with OXO symbol, but without numbers.

What about DE545528 as shown?

This is in a Period 2 (Triang/Wrenn) box with the darker yellow plastic insert correct for this period..

Are their any other variations ?
