Just to add my 'Triple Target', SN 10xx, shown below (& previously displayed/discussed on this Forum). Immediate relevance: Grips, trigger guard hole and "Special"; all in evidence. Interestingly or perhaps of concern, my TL Hand Ejector SN 137xx also shows the 'guard hole'!!! Faintly discernible in my file photos, unknown if visible in Forum pix rendition. Perhaps those trigger guard screws throughout production??? ...Or only on "Executive" models, destined for such as the Kaiser and Elvis!
TLs a certain 'quality aura' all their own!
My take
