[MLW]

Looking for feedback from Canadian customers on Kaslo Shops CN M420 Rebuilt (and what is the difference between the CNR M420 and CNR 420 rebuilt anyways ?)

*Overall quality versus cost?
*Level of difficulty
*Numbers of parts to add on
*Fidelity versus prototype
*Fragility (Resin)
*Compatibility with Atlas U23B
*Ease of building
*Instruction (or lack thereof)



Thanks
