D36 from someone else's hand / D36 out of others hand For a long time there has been a question about the manufacturer of the steam roller shown on the left. This looks like a Wilesco product, but has three clear differences:
----- -------------------------
For quite some time, there was always the question of the manufacturer of the steam tractor at left. He looks like a Wilesco product, but has three significant differences:
- there is no typical Wilesco burner guide
- there is no imprint "Made in Western Germany"
- Only the boiler and roof are made of brass, the rest is normal sheet metal
----- -------------------------
- There is no Wilesco typical torch guidance
- There is no imprint "Made in Western Germany"
- Only boiler and roof are made of brass, the rest is normal sheet
And now there is finally an answer:
The models shown above are NOT from Wilesco or HGL. Wilesco sold a large number of individual parts to another dealer in the 1970s. He first put the parts in acid to treat / paint the surface and then made and sold complete models. However, parts typical of Wilesco such as the handle of the steam valve and the burner guide were obviously not included. Therefore, other parts were installed here.
So these are Wilesco components, but not a Wilesco product. These models have also never been subjected to a TÜV inspection.

And now there is finally an answer:
The models shown above originate neither of Wilesco nor of HGL. I n the 1970 s Wilesco has sold a large number of individual parts to another dealer. He put all the pieces into acid to treat the surface and to remove paint, completed the models and sold them as shown above. However Wilesco-typical components such as the handle of the steam valve and the burner slide were obviously not included. Therefore other parts were used.
So these are indeed Wilesco components, but not a Wilesco product. Also, these models have never been subjected to a technical inspection like the TÜV in germany, which is typical for Wilesco-products since the early 1970s.
