Hypertrophic- MAZAK- Arthropathy !!

Yes, I had a 31813 body, the footplate of which disintegrated fairly early on into countless random shards. I'm (still) waiting to see if RT Models might produce an etched replacement.

 

You may have got lucky with one of the few that had properly mixed mazak, rather than the mutant stuff.

That`s encouraging Horsetan, thanks and for introducing me to RT Models...........

The ebay offering by Rails of Sheffield seems to have a warped foot plate --- Trick of the photo? or a suspicious fault?

Warping is a sign that a crumbly footplate is about to occur.
