The tools I share
References I wish had existed when I trained: exact dimensions, correct terminology, sources on display. Everything is free, with no sign-up, and every figure can be checked. If you spot a mistake, tell me: precision is the trade.

01
Length of pull
The four stock dimensions (length of pull, drop, cast, pitch) explained and illustrated, with a starting-point estimator and the usual ranges, all sourced.

French gun terms
The fine-gun vocabulary translated both ways: bascule, longuesse, quadrillage, jaspage... A hundred terms organised by register, with search.
Open the tool →03
Stock finishes
Rubbed linseed, Tru-Oil, tung and wax: the sourced ranges (thinning, coats, drying times), a troubleshooting table, and the London finish tradition.

Proof marks
Saint-Étienne and Liège: identify each mark, its period and meaning, with source confidence levels. Plus the date-letter tool for Belgian guns (1922-1999).
