1970 vintage cabinet latch and lid support
I was happy to stumble on this thread and have myself successfully ordered the latch shown from Vintage Trailer Supply. The product code by the way is : VTS-557 , Price is $5.95.
Another replacement part of interest for the heavy mirrored cabinet lid is the lid support slider which I also ordered : VTS-629, Price $8.99. Mine with age is hard pressed to keep the lid open. The nylon washer/bearing if there ever was one on my overhead cabinet is long gone.
All the times I've looked at the Vintage Trailer Supply site these items never caught my eye.
