Question about Model 53 front sights|Winchester Sights|Forum|Winchester Collector

As part of my research and writing on the Model 53, I would like to know what sort of front sight they used and if it varied according to the three calibers. I only own one at the moment and it has special sights, so it is of no help so far as standard sights go. I would be grateful if those who own Model 53’s could look at their front sight and tell me what it says and what the caliber is.

The rear sight appears as though it might be a flat top sporting sight No. 22-A
