This Service can be added in addition to the cost of any O Scale Passenger, Traction or On3 Passenger kit. We can round the roof ends here at LaBelle for you. This $20.00 charge includes $6.00 for the Roof Rounding Kit and $14.00 for rounding the ends of the Roof to the proper contour. We can also round the roof ends on kits previously purchased from LaBelle. This price covers O Passenger, O Traction and On3 Passenger. If you have previously purchased a rounding kit from LaBelle, include it with the roof and we will credit you the $6.00 for your previous purchase, so the rounding, with your rounding kit will cost $14.00
