Roundhouse Bertie Part 6 - Some modifications explained

In parts 6 & 7, I explain the modifications seen on the loco in part 5. Included in this part are: paint, buffer beams, springs/sandboxes/oilers, handrails, cylinder covers and chimney cap. Once again, It is me rambling on I am afraid, but I have added sub-titles occasionally to correct or add something. These are my views as a customer of the businesses mentioned. I have no commercial connection other than as a customer and occasionally as a supplier of Chuffers to some of those mentioned. Many of these mods are really simple, but always read the manufacturers' instructions and please do not attempt the more complex modifications unless to are confident to do so.
