Label says Type 192 ? Belvedere?

Valiant spars & Viscounts too were strictly not 7075, but of the same Al-Zn family, DTD 683 I believe. Viscounts were resparred with L65 which is of the Al-Cu 2024 family. Mind you the first Viscount outer wing I saw at Weybridge that was due to be re-sparred was horrifically rivetted – double holes & rivets too long and ‘nailed’ over – no wonder it failed a ground stress test!
Viking wing spar joints I believe were also of DTD 683 & were known to have corrosion cracking way back in ’52 (?).
BTW Canberra ‘epsteins’ were known to crack in storage – not sure what the material was though.

Thanks from me too – very interesting to know that DH also used the lofting on sheet metal plates & litho process – I worked in the Vickers Weybridge Mould Loft in 1959/60 where they used a similar system, but were gradually moving over to plastic film & a photo print process for detail parts & some assembly drawings during 1960.

Looks like its a Vickers Varsity from the drawing number – 648. Cannot remember what the 16 ident part of the aircraft is, only remember that 28 was forward fuselage!

1st pic drawing number looks to be 64816 311 ND, possibly meaning a Not Drawn item, meaning not having a detailed dimensioned drawing – meaning file to fit hammer to suit?

Jetpipe & air scoop shadow do not align with mainplane shadow………..? Nice try though!

Doesn’t look as though it ever had one…..how about the plain nuts as well as having 1 1/2 threads safety?
