But none of these GT’s did.

Now onto Arnhem…
TO – not wanting to hijack the thread – but just for completeness may I show the etch reaction?
The copper in the copper sulphate is displaced by the aluminium from the metal and leaves sold copper residues on the tokens that needs to be cleaned during the etch for it to cut deeper..
Only the exposed surfaces are etched – the etch resist and paint to the rear stop the solution etching in the wrong places.
The reaction is exothermic – so the solution heats up quickly. It is very important to take care with the rate of addition of pieces and cleaning of the metal surface to avoid the reaction overheating.
Once the etch is deep enough – I quench in water and then wash the tokens in solvent before moving to the polish.

I now need to buy Mrs FA a new pair of barbecue tongs…
This Years Tokens
As it is typical Bank Holiday Weather in Cumbria – we progressed further with the Cockpitfest 2013 Tokens.
Just for information – the stages are:
1. Aluminium Bar – guillotined to size
2. Tokens edge cleaned, chamfered and scoured
3. Etch Resist prepared and Printed
4. Heat Tokens to 170C and iron on etch resist.
5. Spray back with paint.
6. Etch with a Cu2SO4/NaCl solution
7. Remove paint from rear with solvent
8. Polish surface
9. Drill Mounting Holes
10. Paint two Gold Tokens for winners.
Repeat above x 60.
They are now printed with etch resist and will move to the next stage.
All remaining stages should be completed this week.
As I am in Holland on business this year,we cannot attend Cockpitfest – so I will post to TO before the event.
Have a good time and I earnestly hope the weather is better than last year.
V1 wing
Atatched are the pics I got in 2011 of what I was told was the V1 long range wing leading edge – pics are from the seller..
It was 2.2m long and I assume it was sold to someone at Speyer.
The V1 rudder I have at the moment was bought in Germany and was definitely painted in RLM76 on one side – just faded to a green colour over time
[ATTACH=CONFIG]216833[/ATTACH][ATTACH=CONFIG]216834[/ATTACH][ATTACH=CONFIG]216835[/ATTACH][ATTACH=CONFIG]216836[/ATTACH]
There have been a few V1 rudders and elevators available – about 5 intact rudders in the last few years.
Most rudders have the push rod from the lower stbd side broken off.
I was tempted by an original wooden front edge of the wing from a Reichenberg for sale at Speyer but it was really quite long!
Thanks Kev
There is a downloadable few pages from a wartime engineers magazine available. It is an article covering a few pages and discusses the Oxford production with pictures.
We downloaded it about 5 years ago and I passed the copy to Bob at D&G as he was working on an Oxford.
I cant remember what the name was – but it came up on a google search back then.
Other wise contact Bob Sloane.
I should correct myself this part is not a casting it looks to be a very thick piece of aluminium (ca. 4mm) and has steel bolts at the bottom edge. The top has been cut off.. the outer edges have been turned over to form a flange for bolting to a lower surface. The inner edge is flanged but curved over.
Even though the numbers suggest a 504/Harrow –
I cannot see this piece being used in a a 504K.
The Harrow had an interesting but different structure:
fourth piece was a corroded aluminium casting.
Just cleaned this up and the part number is
5402874.
There are the remains of two inspectors stamps – circles with 49G .
So not Hornet, Mosquito, Thunderbolt or Auster.
Any suggestions – the parts list suggest Harrow or 504??
As someone who travelled from Cumbria to Shoreham – the current suggestions of North being North Weald, Hendon and Duxford are perhaps still a little “southern” for my taste and geography.
NAM is still a 3 hour drive away from here.
I scanned a lot of old B&W and Colour negatives into the computer using a simple scanner from Maplin.
Amongst the photos from early 1960’s Cornwall was this one of an RAF Launch.
The first part has been cleaned around the numbers and I can see:
B5-14-240 JDZ
B5-14-242
248 in a circle
The Inspectors stamp looks like AUS with 248 below all in a circle.
Auster B5 (AO9)Starboard wing rear section – fillet between glass and wing?
Thank you Sir.
At least one part was correct!
Thanks Bruce – the numbers on the first part read as B5 – 14 – 247 ? then 112 and 247 ?
