Following on from my bringing the '83 Stock blind back into operational condition earlier in the year, I can now report that its older relative is back in use too. Whilst this one didn't have the same electronic-related issues that were encountered earlier, it was still not completely straightforward, owing to the amount of dirt that had accumulated within the enclosure over the years - it was the sort of dirt that was very difficult to remove, but seemed to be able to transfer to any surface very easily! Pictures taken throughout the restoration, along with a video of the blind in operation, can be seen by clicking here. I hope that the work meets with everyone's approval!

Any thoughts about trying to acquire an original style ‘reversed-out’ ‘67 Stock blind ?

I'm not familiar with these; how did they compare to the type that I have?

As you say it shows terminal points where there were no crossovers or trailing points. I wonder why?

Not a physical blind, but the1973 and D stock DVA can / did also show any destination too Always found that a bit odd.

I'm not familiar with these; how did they compare to the type that I have? Layman answer ... The printing on the original blinds was on the back of the blind as opposed to the front. It had to be backlit in order to show anything, if not lit it just showed a white/dirt coloured panel. The object of these blinds was to only show the destination at the front of the train. Someone might be able to get more technical with this.

Ah, I see what you mean - why was this idea dropped in favour of the front-printing method?

Backlit blinds were not practical on other lines because, unlike the Victoria Line, they had sections on the surface where a backlit blind would not be able to be read in daylight (a fluorescent tube can't compete with two trillion petatonnes of fusing hydrogen, even if it is 93 million miles away.)

That's a good point - even the modern LED destination displays struggle in very strong sunlight!

The reversed out blind came about to speed up turnaround time at Victoria when the line first opened. The designers had recognised that the time taken in shutting down and opening up tasks on a 67ts would be too long for the available dwell time even with stepping back. So they left The SB cab blind on the Victoria position (later Brixton) and the lamp was turned off rendering the name invisible. This saved the time taken in turning the handle to display the correct destination.

Were the destinations on the original (post-Brixton extension, anyway) blinds arranged in the same order that they were on the post-refurb blinds? I only ask as the placement of the destinations seems a little odd, if turnaround time was to be kept to a minimum - why weren't the regular destinations of Walthamstow, Brixton and Seven Sisters all placed together - there's quite a bit of winding required between the northern and southern terminii!
I can appreciate that a south-facing cab could be left displaying Brixton and a north-facing cab, Walthamstow, until such times as these needed to be revised, but wasn't the requirement (as I think was discussed on here in respect of C Stocks) that both ends had to display the terminal point of that service? Whether this happened in practice or not is another matter!

Also, Victoria and Kings Cross were regular reversing points so would see a lot of use.

Whether this happened in practice or not is another matter! The point, I thought, of the reversed-out blinds was that it didn't matter what the rear blind said as, without being illuminated from behind, it couldn't be read anyway. On the Victoria Line, at least, it was very unlikely anyone would see the rear blind unless they had already missed the train anyway. I'm not sure what happened when 1967 stock was used on the Woodford/Hainault shuttle - did the blinds even have those destinations available?

The Original reverse blind did have the following Central Line stations on the blind Hainault, Grange Hill and Woodford, these were at the end of the blind, however these destinations did not appear on the Destinations transfer on the Destinations Box, as has been said were difficult to see during daylight hours and especially worse if the Destination Box light was switched off.
I also have restored a 1967 TS box and have a reverse blind fitted, with original 'Gold Transfers' and original destination list transfer.

I'd be interested to see pictures of that, if it's in a convenient place! From which DM was it removed, do you know?

In something of a postscript move, I have some further information to share, in respect of the '67 Stock blind...namely, that I decided shortly after installing it that the blind material itself was in very poor condition, even after cleaning, and so I decided to drop a line to McKenna Brothers, and ask about the feasibility of having a replacement made, using the original as a guide. They were able to produce this facsimile without any issue (my wallet feels a trifle lighter, mind you!); the results can be seen in this video:
Now, I will admit that I did apply a tiny bit of artistic licence while I was having the new blind produced, just in case anyone spots something unfamiliar..!
