Ernst Plank 520 or 520/1 “Hercules”
« on: January 11, 2021, 01:46:45 pm »
The closest I can get on the model number for this one is 520 or 520/1 as the catalog does not have the dimensions... If anyone else has this model, can you let me know rough base dimensions so I can figure out if I have the larger or smaller of the two? Thanks!

Here are the three of them together Nick. They are roughly 6.75, 8.75 and 10.75 inches long the base.

The little bloke has the stack on the top of the boiler and the larger ones have the stack on their own base.

Thanks Walter, so your 10.75 is the 520/3, your 8.75 is the 520/2 and lets hope your 6.75 is different than mine, so we can figure out if one of us has the 520/1 and the other has the plain 520...

I checked with Roly Williams, and his appears to be the same as mine, BUT his flywheel is 37mm, where one of mine is 45mm and the other is quite a bit chunkier at 50mm

Well... dang-it! My two are also 6.75”, so all I can tell you is that ours are the same... either a 520 or 520/1...

By the way, look at my pictures of the two next to eachother... notice the strange fill plug on my nicer one? the top half unscrews and there is a hole through the bottom half. Any idea what’s up with that?

The catalog pictures look like your older fill hole.
The newer one looks like a safety valve, some what, Wilescoan.

Safety valve is built into the pressure gauge. The part that looks like a safety valve screws shut, I’ll get a picture...
