Jan,

Mine are the same except that the tyres on the earlier one are different.

Chris.

I did not notice this variation of the spring. Jan W you write that the spring has been replaced by a washer which is rather a spacer. By looking at some pictures, it seems that this spacer is cast with the gun's carriage and becomes a boss. Am I right ? This boss probably hides a delta washer which has the same use as the helicoidal spring which was fitted previously. If you feel a friction when you move the barel in elevation then there must be some kind of friction component inside.

There is a variation which has not been described here yet. The elevation setting wheel is first diecast and it has four spokes, later is was replaced by a plastic three spokes wheel, the same steering wheel has been fitted on the Austin Champ. When was this change done ?

A delta washer is slightly conical and it is springy.

We discussed the way in which these agricultural tyres should be fitted. As they are not fitted to driving wheels I think that they can be fitted either way but both tyres must be fitted the same way.

Could there be any more variation for this seemingly simple model ?

Jan,

Thank you for this picture, it solves a point.

Jacques

There are 3 versions of the 7.2 Howitzer - 

1) With ordinary treaded tyres and a metal elevating wheel with 4 spokes painted the same colour as the gun.

2) With 'Tractor type' treaded tyres and a metal elevating wheel with 4 spokes painted the same colour as the gun.

3) With 'Tractor type' treaded tyres and a black plastic elevating wheel with 4 spokes.

I have only just received this 3rd one so am pleased to be able to add it to the list.

Chris.
