Dereklefflew you asked about replacing the spring catch on Strand Century Lekos here is what I have done in the past.
I have only had to do this once when one broke and I could not get a spare. My solution was to get a "flip clamp" that you use on the Aluminium PAR 64 can and retrofit this to the diecast lamp housing. This was done by holding the lamp houseing closed. Placing the closed clamp on the lamp housing so that it crossed the joint. Marking around the outside of the clamp with a sharpie. I then seperated the clamp. Placed the first part of the clamp on the housing using the sharpie marks to align and marked through the two holes onto the housing. I repeated this on the other side of the housing. I then drilled all four holes using the correct drill for the pop rivest. I then used the long pop rivets to attached both parts of the clamp. This works fine on my unit. If you are worried about the strength of the clamp and the weight of the lens barrel then I would use two clamps spaced two inches apart.
If you have a spare original clip from the spring clamp then I will have to go into my garage tonight and have a look at my fixtures to figure it out
hope this helps
