Thanks Phil, i'll try that now.Glad you enjoyed Anglesey by the way, did you see any planes at Valley?
If that top bearing dimension is correct at 26 x 48.5 x 15 then you should be able to buy them... this is what came up on Fleabay Australia.They are based in the UK.. there were also a search as wellhttps://www.ebay.com.au/itm/270634303381
I fitted a set of tapers in the early 80s to my 500, just removed one tonight and the top bearing is stamped 26 x 48 x 15. However they don't seem to make that size anymore. When I remove the bottom race I'll post what's stamped on that. There was a 3mm spacer under the bottom taper.
