I had twelve of those things delivered this week and the shipping and customs was twice the cost of the parts !!
Thread swerve coming -
The distributor in the OP's first photo could possibly be a new sand cast copy of an original as the "XF" serial number is usually in relief on the casting and not Dymo taped on - nice work if it is a copy IMO.
Does anyone know the source of these as we need another couple ?.
If you are looking for the block separator, look for the one with one rounded end and one square, like in the photo of restoration parts I have attached. It also needs the cross drilled bolt. Can't find the chromed holder atm. Too many boxes to go through..
