I'm fairly sure that's a German Bosch ZU4, the model number is usually stamped on the brass base, although it might be on the engine side so you can't see it.

These usually have a maker stamped on them, has this one got one?

I'd say it's a tail light, probably European. the clear lens is for the number plate. It's very similar to the CAV or the Rotax. If you Google 'Divers Helmet tail lamp" you'll see similar styled lamps.

I'm sure it's not motorcycle related. I would have said it's an aircraft tacho, if anything, similar to this one;

Ivan, that is interesting, I didn't know that there were any Locomobile Junior 8's in Australia from new. Were there any Models 38 or 48 here from new? There are/were a couple of Model 48's here, however, I think they are recent imports. There was the project that was at the auction in Sydney a few years ago and the red Shannons car that I know of. There is this photo of a car that's said to be a Locomobile taken near Canberra, but I think it's more likely to be a Pierce-Arrow. http://archival-classic.sl.nsw.gov.au/item/itemPopLarger.aspx?itemid=37264 Willie, there are a few photos of a Kellner sedan on Google, could that be the same car today? https://www.google.com.au/search?q=kellner+locomobile&client=firefox-b&source=lnms&tbm=isch&sa=X&ved=0ahUKEwj2qI6H2tzTAhXIo5QKHePrBlYQ_AUICigB&biw=1586&bih=758

I think the bike in the original photo is of a 1916 going by the handlebars (has a cross bar, 17 doesn't). The third and forth photos are of a 1916 Powerplus --the first year of the Powerplus-- which was the last year of the tank between the frame tubes. The second photo is of a 1917 Powerplus and was the first year of the saddle tank. I can't really make out the tank to be sure. 1916 and 1917 have the external throttle and adv/ret controls (the little shafts with uni joints), that also appear to be on the bike in the first photo; in 1918 they done away with these.

That distributor cap is off an IHC E4 magneto. They were used on the tractors in the 20's, like the 10-20, 15-30, etc.

They look like this one. As Ben said, they appear on eBay occasionally. https://au.pinterest.com/pin/90635011227986884/

More likely to be from a stationary (hit miss) engine.

It's an Indian Powerplus, but I can't tell you exactly what year, but after 1916. I can't see enough details of the engine or tank to give you a better ID, as it may be a couple of years later than that.

It's a Solex carburettor, although I can't tell you what it was fitted to originally. The brass washer that holds the fuel bowl on the top usually has the make embossed on it, however, the original washers were sometimes replaced with a normal washer over time and that washer doesn't look to be original. The size and model of the carburettor are usually stamped on the fuel bowl, if they're there.

NZ is right, the three motorcycles in the middle are 1909-10 Excelsiors as well. The latest the Indians could be is 1911, as in 1912 they started fitting the small front guard in front of the front spring, although the could date back to 1910.

DRGM is a German abbreviation, basically meaning it's a registered design. It was used up until the late 40's.

Not from the photos I've looked at, they have a more rectangular cover. The 1907 cars appeared to have the same cover, but the front guards and cowl are different. I'm not sure about the side lights. I can't help you with details about the National siren, and I actually haven't heard of one until now. I can tell you the speedometer is an early Warner Auto-Meter.

Yes, I think it's a 1908 Pope-Hartford, the same as this one; http://oldadstore.ecrater.com/p/21950066/1907-ad-pope-hartford-automobile-for-1908-30-hp The giveaway is the distinctive spring shackle cover on the running board.

That's a lot of cars registered in one state, for only a six month period. I would have thought there would have been more European cars, what about the Austin's and Morrises? surely the FIAT's, and there should be a few of the exotics like Bugatti's and Isotta's. The wording says 'some of the totals', but I think they've left a few out for whatever reason.

It's an Excelsior, but a 1915. The first year of the rounded side tank and three speed gearbox.

Theseare out of an early Tecalemit catalogue, which shows B C D & E.

Thank you both, that's a very good lead. This isn't actually for me, I'm helping a friend out.

I'm after the internal socket for a late teen's Leece-Neville generator. Attached is a photo of the alloy regulator cover, with the socket fitting that it has to screw into. The internal diameter of the socket is 1-1/4".

It's an Indian, but a 1916 Powerplus. It was a one-year only bike, the first year of the side valve engine and the last year of the tank between the frame tubes.

That is interesting, you've gone to a lot of effort here! Excellent stuff. And, I haven't seen that particular PDF file before either. I've used this table to measure hubs and wheels before. I don't know if it'll be a help or a hindrance. I can't remember where I got it from, I guess from a German site. The outer spline dimensions are very similar to what you've got on your table for a Rudge 42 outer diameter, 62.01mm v's 62.2mm. I've got a feeling the original splined Rudge hubs I've seen have a definate 'point' at the tip and aren't flat. I'll look at a couple tomorrow to make sure.

I can't argue with that ID.

Austin 12 from about 1930-31.

I think the car was a Hudson Super Six, but one of the earlier cars, say about 1916-17-18-19? The Houk wheels (25"), Timken diff, front dumb irons, etc all fit.
