Hi all,
Recently I’ve begun playing a gig at a church in Indianapolis that owns their own harp. It is a gold simi-grand style 17 and the number is 3385. Does anyone know how old that would make it, and could someone explain the numbering system?
The 4 digit serial numbers started in 1910 and must have started with the number 1000 or 1001. For many years Lyon & Healy averaged about 100 instruments a year. So the first two numbers of the 4 digit serial number tells you within 2 or 3 years on either side when the harp was made. Your instrument can be dated to around 1931 to 1935.
