It might be lambs tongue but you will have problems finding an exact match. I use a combination of victorian moulding planes and a stanley no. 92 to make them from scratch or build up with repaircare (epoxy resin) and cut back using the no. 92 using the existing shape to blend it in.
Looking at the amount you have to do that would be my approach. I can't recommend substituting body filler for repaircare.
They are a very good design. The moulding planes can be addictive. The results are amazing though. In situations where you don't have appropriate router bits or need a little more finesse they work very well.
