Extending Walthers Gain kit with extra silos

[CN_Kiwi]

Hi,
I am currently building the Walthers N Scale ADM Grain Elevator (Kit 933-3225). It doesn't quite look big enough for what I want, so I went looking for the Add on Silos kit (933-3226) only to find out it is no longer in production and is very hard to track down.
(If anyone has a source for this kit, then let me know)

As an alternative, does anyone know if the silos in kit 933-3218 Medusa Cement Company are the same size as the grain silos (height & length)? Could I use this kit to extend my silos? I have sent an email to Walthers but I am still waiting on a reply........

My last resort is to attempt to build my own silos from PVC pipe but this would probably require investment in the right tools to do the job($$$). To date I have just been using a hand saw for anything that needs cutting.......and re-cutting.

Thanks,
Colin.

The "pack" of 2x4 silos in the Medusa kit is 70 mm x 135 mm.The height is 161.5 mm, including the "floor" and "roof" parts. Hope this helps.

Thanks Lennart.  Looks like it matches the silos from the Grain Elevator kit.
I was hoping Walthers would re-use the same parts.
