Back in 2012 I came across a bloke by the name of John Gramlick behind the wheel of a Commer Knocker.

A lovely bloke and an interesting truck. So much so that I decided to interview…..the truck! ‘Knocker’, as he was affectionately known was a bit of a grump, but very knowledgable about his upbringing. I bring you Knocker the Commer (and of course, John)…..

Kermie: Is it ok if I call you 'Knocker'?

Knocker: I 'spose so. Had to put up with it all my life. Not my fault you know. I didn't design me.

John: It's because when you start him up there's a sort of knocking noise. They use different nicknames in other parts of the world.

Knocker: Yeah but I bet they're not as derogatory. I've been proven to be a pretty reliable truck. Did you know, Kermie, that we were the first trucks to do refrigerated runs from Adelaide to Darwin? The Yanks didn't have it all to themselves!

Kermie: That's cool - no pun intended.

John: The nickname came about because of the engine design. 'Knockers' got a TS3 engine. It's a horizontal three cylinder, six piston design. The pistons in each cylinder are opposed with the combustion chamber formed between the crown of the piston pair and the cylinder walls. The pistons are connected by rocker shaped con rods to the single crankshaft, located centrally underneath.

Knocker: Pretty efficient we were too - especially for a two-stroke diesel. Did you know that Volkswagen is working on a similar design? They're pulling 300 plus horses out of a single cylinder version which can be added to. Imagine a four cylinder version of that motor. You can check it out on www.engineeringtv.com/video/opposed-piston-opposed-cylinder. Just remember we did it first!

Kermie: Seems everything old is new again. So, tell me a bit about yourself.

Knocker: I was born in 1961in England and built by Rootes. I'm a small-cab version and was called the QX model here in Australia. Some of us had split windscreens but mine's a single. I've got what they call the Suitcase gearbox. The 'TS' - as in my engine - stands for Tilling Stevens who made Vulcan trucks.

I was originally bought by a bloke from Walla Walla, near Wagga Wagga and did general haulage from Melbourne to the border and beyond. Then someone else got me and used me to cart fertilizer. I prefer not to remember that period of my life! I finished up with a builder who put a tipper on me. He was the prick who put me off the road!

John: Well you ought to be grateful to me, Knocker. I was the one who brought you back to life in 2003.

Knocker: Do I have to call you Dr. John now?

John: Sounds fair. After all, I saved you from extinction. I've done a lot of work on you. I know it's taken a while but parts have been hard to procure. It was even more difficult when Mitsubishi bought Chrysler who had in turn bought Rootes. Mitsu chucked any spares into a bloody big bin.

Luckily for my mate, Knocker, I'd done my trade as a motor mechanic, back in the late 50's.

Kermie: Did you have a particular interest in the Commer?

John: I'd owned one for a while in a past life and was reintroduced to them when I worked for a bloke at Heyfield carting timber in the scrub. That one surprisingly had power steering. Knocker here hasn't, but he's air-braked. I've even got a trailer for him that I use for living quarters when we go to shows.

Kermie: Does he run and tow well?

Knocker: I'll answer that. John took me to Lucindale in SA to pick up a '48 Chevy and I ran like a charm. I'd just had some new pistons and rings fitted. I used a bit of oil at the start of the run - just to put the wind up him, mind. To give him credit, he has kept me as original as possible.

Kermie: Thanks Knocker. You look pretty good for an old banger.

Knocker: Old Banger! I'm only 50 you know. John's 75. If there's an 'old banger' here it's him, not me!
