If it is any help I had my Grimes ST250-24 landing light overhauled by these guys http://www.avliteaviation.com/index.html – excellent service and quick too.
They do not have any original bulbs left – unobtainable – so I had it converted to a modern sealed beam unit.
I have not fitted or tested it yet as rebuild is still on going. They told me that spares are getting scarce – so better get in there quick!

I have a somewhat similar situation. I have two of these lights – one in each wing – Grimes. The little pot-metal block that holds the axle of the large gear has crumbled on one of mine. I’ve got the unit out of the wing and have drawn up the part and will try to make a replacement. I think I have properly recorded the connections, but will proceed cautiously. The biggest problem for me is to get the limit switch phased properly – in the right “range of motion” so the light does everything right, i.e. extends, lights and retracts properly. There is some adjustment. I’ll likely jig it up on the bench to get it right before re-installing the unit in the wing. I’ll have to make the little replacement block in two pieces to sandwich the axle bearing, which was cast into the old pot-metal block. I’ll probably use a little J-B Weld to ensure the hold on that axle bearing. I’m planning to machine the block from aluminum. My airplane was built as a F24W40-A and is now a 41-A as of a change to the 165 Warner back in 1951 – N28522 S/N 136. Inside the little oblong can covering the limit switch of the failed Grimes unit there was an inspectors sticker dated 1934 – new, like it was just put there yesterday! That Grimes unit is 6 years older than the airplane. That’s archaeology for you.
