Christ knows how you'd price such a unique plate, perhaps list it in the Sunday Times with a stupid price and see if anybody bites.
Is that a Honda 50 cc twin? I notice it has quite a 'modern' frame and what looks like a front bicycle rim type brake.
Based on a Japanese book on Honda racing bikes, I think it's a 1966, 9 speed, RC116, 50cc twin, 35.5 mm bore, 25.14mm stroke, 14hp @21,500 rpm, 109 mph top speed!
doesn't explain the numberplate though, road is windy so not many go banzai here unless you're just a nutter
Deffo... my father was a member of a gun club and although handling the pistols/rifles gave me the heebie-jeebies, their engineered mechanical working was always had that feel. See Tuco in the gun shop The Good, the Bad & the Ugly:
And whilst on the topic of lovely clicking ratchet type thingies I found this in undergrowth down the lane and after a good clean it came up pretty nice and has got a real lovely revolver cylinder like click to it. Damned if I know why it is designed in that manner though. Answers or suggestion on a postcard.
There are many noises that do it for me, but in a similar vein to this is the satisfying clunk of a properly built old car door shutting. One of my first cars in the late 80's was a very tatty 1968 3.5l Rover P5B, sold to me by an old gent who made a big deal about the solid feel of the car, and the safety afforded by the heavily built doors that shut with a lovely Clunk. I felt a bit 'duped' when after a couple of months I stripped the drivers door card off to fix the window winder and discovered @6' of Galvanised chain in the bottom of the door.
Scaffolders Spanner. I believe sometimes referred to as a 'Podger'. No doubt fell off the bed of a lorry driven like it had been stolen.
There's a fundamental error in that scene. Tuco builds a gun by combining parts from a Colt Dragoon and an 1851 Colt Navy. The cylinder is still one with percussion caps (you can see the nipples for these at 2:11 in this video). However, he then proceeds to ask for cartridges and loads them via a gate. It is possible to convert the older percussion revolvers to cartridge but the cylinder would need to be changed, to one without nipples and straight through, along with a frame with a gate. I have a couple of 1851 Navy, family heirloom.
