Snipe Trailer - Correct Bearings

[MrHeadsocket]

I have a snipe unbraked breakback trailer that needs new bearings. I have researched the bearings needed as it's an older trailer (the code on their website for it is A17/500). I took a quick look at the back of the hubs whilst they were still on the trailer and could see what looked like a seal..

I found on the Snipe website it needs bearings with the following part numbers:

L44643L, L44610 and seal L44600L

So I found these: http://www.bearing-king.co.uk/bearing/l44643l-l44610-l44600la-timken-sealed-type/3105

However, these look exactly the same as the bog standard 1 inch taper bearings, like these:

I have a set of the above (eBay) bearings, but I can't decifer whether I can use these or not, any advice would be appreciated!

If you cross reference the bearings you will probably find that they are the same as 99%of older small trailers use the standard bearings you can buy off eBay for peanuts
The rear bearing has the seal attached to the inner race I guess that's what you have read the number off
