Wanted: TW Superslim Whitworth/BSF or BS Wrenches

[amecks]

I have a partial set.  These are double open end wrenches marked in Whitworth (W) AND British Standard sizes (BSF).
Needed:
7/16W 1/2BS - -x- - 5/8BS 9/16W

7/16W 1/2BSF - -x- - 9/16BSF 1/2W   *** UPDATE 10/3/14 - now have these three

5/16W 3/8BSF - -x- - 7/16BSF 3/8W    ***             "          "

3/16W 1/4BSF - -x- - 5/16BSF 1/4W     ***             "          "
           
Will buy or trade other tools.  For Whitworth trades I have a Superslim 3/8W 7/16BSF x 1/2BSF 7/16W and a Snail Brand in the same size.  Have other wrenches, perfect handle screwdrivers, etc.
Thanks
Al

I've never found the 1st size, that's maybe a special.

I have available the next three, $5ea + $15 airpost, paypal preferred.

PM me please.

Thanks.  PM sent.

humber2 sent me the three Superslim wrenches - they are in nice shape - thanks Peter.

I have found that there are at least two more available larger sizes;  although it seems there should be at least two more from 9/16W to 5/8W if you follow the pattern:

11/16W  3/4BSF - - x - - 11/16BSF  5/8W

3/4W  7/8BSF - - x - - 3/4BSF  11/16W

also the one marked BS:

7/16W 1/2BS - -x- - 5/8BS 9/16W

The two sizes that may be available are;

1/2W  9/16BSF - - x - - 5/8BSF  9/16W

9/16W  5/8BSF - - x - - 11/16BSF  5/8W

Confusing as all get out, I know.  Each wrench has one size from the previous wrench - plus the confusing double standard markings. 

Thank you.

Here's my take on these...

Smallest is 1/8 x 3/16  I use only the WW dimension but all have the BSF size too.

7 sequential wrenches follow ascending by the 1/16 WW step increment.

3/16 x 1/4
1/4 x 5/16
5/16 x 3/8
3/8 x 7/16
7/16 x 1/2
1/2 x 9/16
9/16 x 5/8

After this come the 1/8 increments

9/16 x 11/16
5/8 x 3/4
11/16 x 13/16
3/4 x 7/8

All these sizes are in my collection, I'm sure there are a few bigger ones to find.

Thanks Peter.  Very helpful.

I don't know if I will attempt to collect every wrench as there is some duplication.  As you point out some are sized by 1/16ths and others by 1/8ths of an inch.
But I will keep watching eBay and see what's out there that's affordable.
I will probably make a checklist anyway of confirmed sizes.

I have a wrench that looks exactly like these Superslims marked in Ford script "EnFo" and size 5/8AF x 11/16AF.  This must be a T Williams wrench don't you think?

[humber2]

Enfo is the trademark for English Ford.

That wrench is a TW and would have been in the toolroll for Ford car, Thames truck or Fordson tractor.

Ford never used WW or BSF threads but you will find those threads on their Lucas starters and generators.

You may also find cad plated TW wrenches which were supplied in Rover and Landrover vehicles.

The measurements on these wrenches make my brain hurt... but, I found 3 of them in giant buckets of tools I picked up at a yard sale. If they're what you're looking for, send me a PM. :)
