Potterton PTT2 cylinder stat, very rare to find these days. All as new in their boxes, boxes slightly soiled due to being in storage..
Pic attached of them after being fitted. It appears I have two types of PTT2.. Red box version that's grey in colour and blue box that are white in colour. Otherwise will send either or whatever's available. I have a few more of these come into stock but they have come in at higher price. Possibly the last to become available in the uk.
