How Much Does A Good Trans-Oceanic Cost on eBay?
Below is a summary table for sales over recent years. The raw data for this summary may be had from here as an MS Excel .xls file, which shows the number of completed sales for each model type per month over differing price bands, the cumulative totals, and a calculated average price per model based on those totals.
Note: data was extracted by manual examination of the results of a 'completed items only' search using the terms 'zenith trans* -transistor -switch' in 'All Categories'. Searches were performed about every 14 days with a suggested margin for duplication error of 5%. Ebay now only provides 10-14 days of historic data free of charge.
On the suggestion that this represents a not untypical series of transactions, there are some interesting points raised. Given the production numbers for each model, we would expect to see very many more of all types of the 600 series than any other model. Bryant & Cones give those figures thus:
- 8G005: 110,567
- G500: 89,681
- H500: 245,544
- 600 Series (all variants): 269,099
- R-520/URR (Militarised H500): 7,218
- R-520A/URR (Militarised 600): 2,973
The 600 series represents the maturation of the tube-type Trans-Oceanic design and it was one that incorporated many consumer-oriented features - such as the dial light, log charts and cord retractor. This has kept its popularity very high amongst used examples.
