dolls head gearbox identification

Forums

I have a dolls had gear box trying to identify its a cast number of 1945-49 N8001 numbers on the side G15 169 then has on main case SN 19786

thanks for your help

The SN 19786 would indicate it was built between 1948 to ‘49.

The ratios fitted in the box would give an indication of what it was fitted to. These were normally stamped on the outer casing.

For instance as for a 1949 500T, Big 4-WD it might show 1, 1.47, 2.39, 3.67

There is likely to be more info on the website if you search Dolls Head gearbox

Hope this helps

The gearbox code G15 is for the International, so should have close ratio pinions (gears)
