A while back I promised to periodically post plans in my collection.
Here is one such. The grip car here is the later type, with straight side posts. Earlier grips had posts that curved in at the top.

I've reduced it quite a bit to minimise download time.
If anyone wants a slightly better resolution copy, perhaps for modelling, just email me off list and I will be happy to send
