"Can anyone suggest what this might be"?

Awww can i guess...garn let me! Uhm, its an Engine! lols

Naaa Polybus ive got no idea....But id love to know more. Solid head reminds me of old compressors and sidevalve V8s. Its really cool, hope someone knows as nothing on it resembles any engine im familiar with. 30s or 40s might be the age due to its appearance, but industrial often carried old styling well into more modern times. Hmmm im liking all this stuff your digging out:) keep us posted on this, im really keen to see what you can do with it:)
