[3] In 1927 Traylen was elected Fellow of the Society of Antiquaries of London (FSA) and became its local secretary for Lincolnshire and Rutland.

[4] While Traylen tended to concentrate on church restoration work and Lenton on secular and domestic buildings, Traylen was a forceful advocate, protecting, recording and rebuilding historic buildings in a sympathetic style if demolition was inevitable.

Examples are: In 1934 he weighed in strongly against the inspectorate of the Office of Works, when they claimed that nothing of historic value had been found during the removal of the mound of Stamford castle, for a bus station.

He also preserved the threatened 17th-century building behind the Stamford Mercury office, which was re-erected on the Sheep Market frontage of the bus station.

Traylen designing a large number of war memorials: e.g. Broad Street, Stamford, village crosses at Apethorpe, Easton-on-the-Hill, churchyard crosses at Belton-in-Rutland, Collyweston, Thornhaugh, Werrington, lychgate at Weston, Lincolnshire and many other memorials: panels, tablets, lychgates, doorways throughout Eastern England.
