Looking at the book again (Vol 3), the five-digit numbers started in 1918 with the move to Holloway & Naughton (no. 36576). A series ends in 1925 at no. 41891, then, after 1929 under Skimin & Wood the numbers start again at 84090. It would appear that yours falls somewhere between 1925 and 1929, when still under Holloway & Naughton. If you PM me your email address I can send you the scanned pages.
