Rob, Yes..exactly what I think, the buckle looks right but the prongs look like no Imperial I have ever seen. Looked at closely they are extremely sharply pointed, unneccessarily so. There is also another unusual trait to these prongs..it appears that wire was used to hold them on for the soldering process? Another thing I have never seen. I am curious to know if the roller tube is split? It is not shown in the photo's. Jerry Burney
