Guide Headlamps

When looking for parts on the interweb, it never ceases to amaze me at the apparent knowledge that people have in their heads but never document for others to use. Case in point......

Guide branded headlamps.

My cars, whilst substantially made in Australia, used Canadian Delco Remy electrics, then Bosch, Canadian wheels for some time, AC gauges, and American know-how. They were a GM product after all. The engine was developed from an Opel 6 cylinder.

It had Guide 7" headlamps GM part no 925756, for the assembly, fitted from 1948 to sometime in 52 or 53 when they changed to Lucas.

Lots of cars had Guide headlights fitted so, I thought, my particular lights will have been fitted to another car, a Chev most likely, as they wouldn't have made something specially for the Holden.

But there doesn't seem to be a source for finding out which light models were fitted to which car model? If there is please inform me and I'll pull my head in but here is a chance. If and when you know, please document here, which Guide Headlights are fitted to your car. And if you think you know where I can get a set for my cars please PM me .

When I do find something it will say, "may fit Buicks, DeSoto's" etc of the time. Not much help when you don't know what was fitted to those cars.

Please help relieve my frustration.

(Next on my quest will be Delco Remy electrics as you cannot get parts for starter motors here anymore and I will need to raid my US friends supplies.)

Guide Part No: 925795, Model No: 622-36, GM part No is: 926023

From Ebay - This is a start...

BUCKET ASSEMBLIES

These are original Guide Lamp Division General Motors Corp NOS COMPLETE ASSEMBLIES. Guide Part No: 925795, Model No: 622-36 in original boxes. The GM part No is: 926023. They fit the Buick, Olds & Pontiac cars.

These are a sealed beam unit. From another site... (http://www.jalopyjournal.com/forum/threads/1948-51-oldsmobile-head-lamp-assy-%E2%80%93-nos.954363/)

They fit

1948 Oldsmobile only Model 98,

1949-50 Oldsmobile All Models and

1951 Oldsmobile only Model 88.

They also fit Buick, Chevrolet and Pontiac automobiles but you need to check what specific models they fit.

'38/39 Chevy COE truck also has the 682 (682-C?) Guides, but they still have the small light bulb and reflector rather than the sealed beams.

'36 REO (Car) has the Guide Headlights

According to your illustration they used bulb type headlamps. In the US and Canada, sealed beam headlights were mandatory from 1940 on.

So, you would be looking at pre 1940 for a start, and there may have been design changes between 1940 and 48.

This may be why you are having trouble finding the same lamps used outside Australia.

I can see you are correct Rusty. They seem to be a mix from, perhaps, the ones used on a '39 Chev to a '40 or later. The only difference I can see, from initial investigations, is that the parking light on my reflectors is close to the centre, near the headlight globe, rather than near the circumference. I have found two Guide catalogues from Don's Bulbs which make it clear that US had T3 models from 1940 on, sealed beam, but sort of match a mix. I will photograph mine in the near future and post just to see if there might be more information forthcoming.

From my part no. 925756 it would seem the ones shown above, from ebay and elsewhere are closer from the bucket to door but differ in the lense and reflector dept.

Anyone know of a Guide catalogue from the mid '40s? the Holden was developed post war and released 29 Nov 1948.
