d2 antenna extension unit restoration

I won this relic lot in very low price, its translation as: 'Antenna part extension Specially accessories radio station Fu.A1 Torn.d.2 Wehrmacht'.

Didn't know it could be restore or not, but when compared with my d2 antenna, found it hope to loosen it from the base, as the bracket is made of copper and the shaft is iron.

After studied the photos and compared with my antenna base, found its really the parts of the d2 antenna extension unit.

Dropped it into vinegar for 24 hours, then in WD40 for a day, still can't turn a bit, but knocked it off the base.

The only solution left was by heat, tried to heat it at the stove, and it turned a bit, repeated couple of times, its finally released.

The whole unit are completed, but still needs sockets and wires, needs more information on it.

The complete set, the long pole is BW, will get a period one later.

Now the unit is almost completed after added the wires and ropes, but the  two metal rods are temporary, unable to find 8mm diameter aluminum rods locally, had to purchase from ebay.

Also can't find thick HBT strap, the solution is to glue two thin HBT strips by cloth glue, to form a thick strap, the buckle is from British 58 webbing, then secure by screw and washer and painted black.

The 8mm aluminum rods from UK was here.

To bend the small loop, had to heat up the metal, its became soft and easy to shape.

Quiet similar to the original, lucky to have it for measuring the sizes and details.

Secure the rod and the housing through the hole on the rod.

Bought these BW tent poles for the metal end tube.

 Now the end tube and the aluminum rod are both in position.

Its time for the wires and rope, lucky to find the suppliers locally:

Counterpoise wire:  Rubber coated wire in 3 mm diameter, very good Japanese quality, may be a bit harder than the original, also good price too.
Length 178cm plus fixing.---185cm x 4

Guild rope: Only found cotton/linen mixed rope in 3mm diameter, still looking for full linen rope which is closed to original looks and firmer.
Each rope is 300 cm in length.
Sliding blocks: should made of 3mm thick pertinax, 10 x 50mm x 4pcs. But found only Bakelite.

The relic ring clip is heavily corroded, unexpectedly found simile clips available locally. 

The four holding screws are unable to lose, had to drilled into the holes and glued the wires, then secure the ring, had to retread the old screws holes, and its works likes 70 years ago, holes all wires firmly in place.

The end loops of the wires are perfect excepts too shine, had to bend the wire in an angle to fits into the brackets

Quiet difficult to saw Bakelite, must ware face mask for its dust.

.  

The ropes has a difference arrangement, quiet soft due to cotton contain, but looks nice when finished.

Linked wires and ropes together to form a full 475 cm long wire system.

Tried to search for the length of the pole for days, thanks God the one and only information was also from WAF, the total length is 58 cm,

The ordinary 24.5 mm dia wooden stick available on the market fits perfectly into the main unit and the bracket.

Trimmed the tip to fits the aluminum tub.

Glued one more layer to form the thickness of the end tube.

Dyed the raw wooden stick for shade of brown.

Fits nicely with the tent pole when without loading.

Sprayed 'Rubber Black' after sand smooth the two layers.

Fits well the 6mm dia temporary rod, while waiting for the 8mm dia rod from ebay.
