Some of my floorboards need replacing but I am struggling to find something similar. The house was built in around the 1930s. The depth seems to be around 22mm. The width including the tounge seems to be around 130mm. I can see where some have been replaced historically, they just used what looks like pine and I guess cut it to size. I popped into a builders merchant today and the best they could offer would be 5 x 1" and cut it to size with a jigsaw. I can certainly give this a go. In any case it would be hard to get the tongues reinserted as I am not replacing the whole floor. Would be grateful for some ideas and options. Thanks in advance.
