I live for the CABE
This c.1910 Mead Sentinel was originally mine. I acquired it from Dave S. many years ago and sold it last year to Ed from Philly. I think it bears some resemblance to your Admiral, especially the seatstay bridge and the rear dropouts. Unfortunately, I did not note the serial number on this one.

Up for consideration is this as found antique 1910 Mead Sentinel Boys 28" Wood Wheel TOC Bicycle... This original survivor is in fairly nice overall condition with a few surface stretches / blemishes, Troxel saddle has few edge cuts and tires are dry rotted... Rear rim also has a mind spin hop...
