Dating epiphone basses
Note: Theoretically, such SN gaps may include a small batch of a third model.Note: These extrapolated totals in the right column of Fig.And the estimates will keep getting more precise as the database of documented SN/model pairs is growing. SNs of Epiphone electric stringed instruments Epiphone used several different SN systems for their electric stringed instruments over the years (see Fig. From 1936 to 1942, all electric instruments appear to be numbered with ascending SNs representing a chronology of production – similar to the SN for acoustic instruments (SN systems A B).The documented SNs start around SN 25 and end with SN 7219. Understanding Epiphone's SN systems – number ranges assigned to model batches 4. SNs of Epiphone amplifiers Notes Bibliography Epiphone's stringed instruments of the 1931–1956 period typically show a visible serial number – high-end models the same way as lower-priced instruments. Epiphone acoustic instruments: Dating of serial numbers – revised SN/year charts 3.
ranges of SNs exclusively assigned to one model (see example in Fig. Note that in many cases the very first and last SNs of a batch cannot be determined as long as there are SN gaps to the adjacent batch of a different model.Extrapolation algorithms tentatively attribute undocumented SN/model pairs in gaps between two (assumed) adjacent model batches – see example in Fig. 4: Extrapolation of SN/model pairs between two assumed model batches (example): The 6 undocumented SNs 55236–55241 are likely to include models of the previous batch (=Triumph) and/or subsequent batch (=Blackstone), although their relative distribution is not known.Our applied extrapolation algorithm equally assigns 50% of the missing SNs to the previous model and 50% to the subsequent model – in this example 3 Triumphs and 3 Blackstones.This means: Epiphone's ascending SNs reflect a chronology of production.Based on these findings that ranges of consecutive SNs were assigned to batches of the same model, we can extend our research: To reconstructing missing model production data – by using interpolation and extrapolation algorithms on our SN data.
