$products_name on tpl_product_reviews_default.php

I've noticed that the $products_name string contains the following data (on the end) only when the current page is tpl_product_reviews_default.php.

<br /><span class=\"smallText\">[PRODUCT-MODEL-NUMBER-HERE]</span>

Is there any reason for this? I've noticed that the $title string returns the product name without the above code on the end. Would that be the correct string to use on this page?

Thanks in advance! :)

You can see in the header_php.php code for that page that the model number gets appended if it exists:```
if (zen_not_null($review->fields['products_model'])) {
$products_name = $review->fields['products_name'] . '<br /><span class="smallText">[' . $review->fields['products_model'] . ']</span>';
} else {
$products_name = $review->fields['products_name'];
}

Thanks for this. It's all beginning to make sense! :)
