    73 Model year bus production dates Aug 72 - Aug 73
     
  3. The Devon one didn't have a trip counter, so perhaps that was specific to microbuses or an optional extra?

  4. Have you got those instructions for the 3 lever controlled 1973 model year?
     
  5. Mine has three metal heater levers too.

    I think most of the 3 lever crew have 2 red & 1 blue. Yours is probably uber rare limited edition

  8. Great, thanks.

    Have you got the rest of the 73 manual as well?

    It says one of the levers operates an electric fan?!

    No mate. I let it go with my van. I think the snail fan was on the type 4 engine versions only.

  10. As far as I'm aware, 4 lever controls have 2 separate cold air ones, one for each flap. Then one red lever diverts hot air out of the totem pole vents, the other red lever controls both heat exchangers. 3 lever controls just dropped one of the blue levers so both flaps opened and closed together.
    On type 4 engined vans with the snail fan, there's a switch(switchable earth maybe?)at the bottom of the red lever which controls the heat exchangers so when you push it right down(open) it turns the fan on.

    Seems right. You're conversion is probably the SO72 with the light veneer interior!
     
  13. My van started out life with a 1700 type 4 engine, but I only had 3 levers (one of which I think ended up in Malc's van eventually :) ). I now only need 2 (one for fresh air vents, one for the totem to divert to screen/totem vents) due to the fact I also now have a 2 speed fan from the scooby heater box.

    Interesting about the vents labelled 13f, I have the holes but not the levers, and in the end I blocked off the pipes for those vents from the outside, because they were letting water in during wet weather as they weren't connected to anything (previous owner corner cutting strikes again).

  14. 13f is for pre August 1972, '4 lever' vans, look at the next diagram to see what you should have had on your superior '3 lever' van!
     
  15. I have the 4 lever controls and have a type 1 engine. And it has the electric fan when put in the same position

    Do you have a picture of the fan. Is it all original?
     
  17. There is no fan in the engine bay. And it does not have the ambulance fans fitted. Where would the original one be? I have tried to find it before.

  20. On a separate theme.... My Ashtray has the gear locations etched into the plastic front ( not a stick on decal ). Generally Ive only seen either plain or textured fronts - so was this a particular year thing ?
