Manor Books was a direct continuation of Macfadden Books after the that Publishing Company decided not to publish paperbacks anymore.    

(info by Kenneth R. Johnson)

And here's a little info on Manor's numbering system from Grant Thiessen:

Manor continued with the sequences used by Macfadden, and then changed as follows:

around 150-106, Manor continued with numbers 15xxx $1.50 cover prices

16xxx $1.65 cover price

17xxx $1.75 cover price

19xxx $1.95 cover price -- also 23xxx

22xxx $2.25 cover price

around 75-483, Manor continued with numbers 75xxx 75 cent cover price around 95-228, Manor continued with numbers 95xxx 95 cent cover price around 125-146, Manor continued with numbers 12xxx $1.25 cover prices

odd example: the 1973 printing of The Pawnbroker uses number 125-146, the 1974 printing uses 12146, which makes it hard to pinpoint the exact transition points of the numbering sequences
