If anyone is looking for a cheap way into having a go at lining their own locos or coaches I have 3 Bow/ruling pens that are surplus to requirements. I bought these when first starting out and used one to line the Midland milk van shown on one of the threads. At the time I bought them a gent on the LNER forum asked me to buy one for him too and he has used his to line 2mm scale coaches Although I have only taken a single photo of them all, I am asking £5 each plus postage at cost.
