Actually managed to get in touch with Chris Holloway, he did not have access to the full records (in storage), but was able to provide the following from the ledgers (that I could read):
Retailer: 535 (Leech and Sons)
Serial: 6275
Barrels: Best Damascus
Action: Stanley 31745
Price: 100 (this is even higher than the 88 list price in the 1925 catalog)
Description of Action: Treble Concealed
Fence: Leaf
Locks: (Illegible) Ejector
Engrave: BLANK
Finished: BLANK
Sold: 30-May-1908
As you can see, the features match up very well with the model 3900 in the 1925 G&S Holloway catalog and the features on my gun even though it was made much earlier.
Thanks to all who rendered assistance in chasing this information down. Very excited to have it!
