Tim Green´s report brings up a side window engineering issue with respect to his wonderful Aero Minx project:
"I bought this car which was a four seater tourer as a collection of bits in boxes. I already have a tourer so didn't really wish to build another one and decided to build a copy of the much rarer streamlined saloon that was unveiled at the 1932 Olympia Motor Show. There are a couple of surviving examples of the later 1934 saloons so I had at least something to copy and these examples backed up by a handfull of old photographs were the basis for the project. I have been working on the car now for about two years and am edging closer to being able to get the ally skin on. I am having a bit of a problem currently with window winding regulators as I have no idea how to engineer them or from what ! Any suggestions gratefully received as I am a bit stuck."

Editor: Tim, you probably will receive much better suggestions, but it may be worthwhile to think about the very simple construction as used in several vintage French(?) cars. A canvas or leather strap with holes like in your own buckle. The strap is attached to the bottom end of the glass while the other end is within your reach. With the window closed the strap is long. To open the window just unhook the strap and hook up again when the window has 'dropped' into the desired position. Vice versa to close again. Works perfect, looks elegant.

I did try to utilise the morris regulators but the single arm meant a rather lopsided lift and wasn't very good at all. I then found a pair of Riley twin arm jobs which, when eventually fitted correctly lift the windows really nicely. The car is all but finished now so will add some pictures of her when I can.

Thanks again for more recent comments. The car is now back with its new skin and I am starting again on all those hundreds of little jobs including said regulators. I am experimenting with morris 1000 jobs which look like they will be OK. what I may end up with is windows that will not fully lower but I am fine with that, half way will be sufficient to pass an arm through for steering from outside (in case of breakdown!)or get ventilation while on the move. I have jerry rigged a version with a plywood 'glass' which worked just well enough to encourage me to pursue it. I will report back with progress.

Tim - only just seen your query so probably too late. This is solved by having the window glasses cut trapezdoidal with the front and back sides parallel and fitted into front and rear slides parallel but angled and fixed to clear the rear wing cut-out. Thus the glass appears to slide forward as it drops. The top of the glass is then cut to fit the shape of the door top.

The young lady in the period photo is holding onto the window winder, so the window can't drop on a strap or slide. Yes, it's a 1934, not a 1932, but no reason to suppose the window mechanisms were different. Probably the rear edge of the window moves down a slanted runner or track (what is the proper word?) that is parallel with the front one, which permits the window to clear the rear edge of the door where the hinges are, and also mean that the windows are fully supported all the way down.

I see a problem with the depth of glass ,
it will only open 3/4 due to the hinged side dictating length of glass, a simple solution is a double runner & a pair of sliding windows, the alloy track is available from the usual suspects, you would need a curved top vent in glass & a frame to take the top , below the vent.

The leather strap idea is practical- but would lack authenticity. Some time ago I broke the winder (a casting) on my 1933 Talbot and spoke to Archers of Great Dunmow about it. They produced an enormous catalogue and, rather incredibly, I discovered that my winder was still being made! In those days a lot of fittings were proprietory parts supplied to many different car makers, and some parts are still made today for the now thriving preserved car market. I don't know if regulators are also in that big catalogue, but there's no harm in asking. Archers number is 01371 872802 (they restore all sorts of pre war cars).

Thank you all for your helpful comments. I think taking a peek inside another 1930's car door is going to be the answer. Perhaps I will find a wreck at Beaulieu at the weekend to record. I have been offered a morris minor regulator so will get that and see if it can be made to work somehow. I will let you know how I get on

The LDV 400 and "Convoy" light commercial vehicles that were produced until comparatively recently have very well made hand wound window regulators that are easily adaptable and are very similar in design to their pre-war counterparts. Most vehicle dismantlers will have at least one of these vehicles in their yard.

you need to decide where the handle will be then measure the length to somewhere near the center of the bottom of the glass in the open position, push the glass up to the top (closed)and measure again, that will give you some idea of the lenght of the regulator to use

tim, must be plenty of prewar regulators lying around, (all those saloons turned into tourers. The amount of 7s, pops, that where made, could use one of those. Or anything from a more modern vehicle they are usually in my experience only screwed onto a lump of wood in the door. could use any modern too as no one will see the thing and just get some old winders... more tricky is the shape of the door, looks like to me it will need to slide down the A post as the rear has that little hipcup from the rear wing in it. dont forget that sometimes the quality and fit of these old cars was not what we would like to think is was, some where amazing others bloody awful Best of luck

The Editor's suggestion works very well. The same system as used on early railway carriage windows.
