This showed up on my FB page and I had to share,

Wow. I thought I knew my flathead schmidtz, but I've never seen that one before. Thanks.

Might that be an Australian rod?  I'm not seeing a drag link where I think it should be in the picture, if so then those heads might have been locally made there.  

With two exhaust ports per side, apparently those heads move the exhaust ports out of the block...very smart move.  Easier to keep the engine cool, for one thing.

That picture was taken at a London car show. It referred to a "Firth Conversion"  I will mostly spend a good part of my day searching for info on this

Never heard of Firth.  The heads look a lot like the Smith "Jigglers" which were USA made.  Those too are rare pieces, especially the V8-60 version.

As Mark B. said it looks like the Smith Jiggler.

A neat Little Engine. I wonder what connection it has to the Firth Conversion?

Of Course, but interesting to me that Convergent Evolution seems to have caused these two engines to look similar. I wonder how old the Firth Engine is?

After looking at their FB page I would guess the Firth is  a more recent design,

I thought so too. I wonder if the Firth Folks have seen and read about the Jiggler. As obscure as the Smith Engine is, it is not totally Unknown. Seems that somebody could take inspiration from it.

[Little Timmy]

I would. L O V E  to hear it run.

The VCG Resins Jiggler is super cool for any exposed engine hot rod!  I just had to put it in my 32 build.
