MCGRATH Semi trailer

[John Mackie]

I have recently acquired a TRAILER 4 WHEELED 7 TON G S (AUST) No 1 with converter 2 Wh. They have 20' 8 stud wheels. Definitely original. But the front axle has been converted to 10.00 singles ( they cut the rims up and welded 7" spider rims to the centres).
It has Vacuum brakes on the rear axle, the air tank, relay valve and master cylinder are there but not a air chamber as shown in one of the earlier photos. If anybody has a PBR T110 combination master cylinder unit to take air and vacuum power cylinders. Please let me know as it may be pulled by a truck with air brakes.
It has a cast iron ID plate the full length of the steelwork between the rear shackles with the serial number 84?? cast in it. The dolly has had a similar plate but only the boltholes are there
The top piece of the round front and spare tyre carrier have been cut off. The floor needs A bit of work,!!$$!!
In the 1960's I bought a very similar trailer it had 8 stud rims but a square front and was number 8244.
