Conversion tables.

The following general rules are explained in this book. Example: applying the rule B $\rightarrow$ 19, List number B.109164 becomes Group number 19109164 (``million'' series). See above table...

bolts:

B $\rightarrow$ 19

studs:

S $\rightarrow$ 29

screws:

SC $\rightarrow$ 39

screws:

TS plus six figures $\rightarrow$ 49

screws:

TS plus five figures $\rightarrow$ 97 (? more likely 490)

SEMS units:

M plus five figures $\rightarrow$ 590

SEMS units:

M plus six figures $\rightarrow$ 59

rivets:

R plus five figures $\rightarrow$ 690

rivets:

R plus six figures $\rightarrow$ 69

nuts:

N $\rightarrow$ 95

other numbers completely changed:

B, CB, D, DS, JP, M, N, R, S, SC, SCR, SPN, SQ, T, WS

others ditto below 1000 only:

P, W

Million series nos. to be used on all drawings from this date January 1959. P, H, K series continued to be used for numbers higher than 1000 and may now be included in the Microfiche collection.

The new numbers are listed in Books 1-4 except for the 19-- numbers noted above.
