Thx for the replies, guys.
Its for a long term project. I want to build a station replica of Swartkops down in the Eastern Cape, just out PE. Ive grown up there as a kid for almost 30yrs. The station area was my playground as a little boy.
On one of the station towards PE, there are 2x double slips in serie and on the other end there are also 2x double slips - not in serie. One slip is a must for its purpose, but the other (double) slip is not really of use. A single slip is what its suppose to be.
I have 3x d/slips already and thought of bringing the 4th one in as a s/slip. But if I could get a d/slip, it wouldnt matter. First choice, s/slip though...
Regards, Morné.
