No, that is NOT a Weller W60P. In fact I don't think it is a rebadged Weller at all as it is not magnastat.
The RS part numbers for Andrews iron are:
Handle 544-594
Element 315 deg C 544-601
Element 370 deg C 544-617
Element 430 deg C 544-623
Screwdriver bits
0.8mm 544-588
1.6mm 545-216
2.4mm 544-586
3.2mm 544-550
Needle bit 1.2mm 544-572.
These are long discontinued. I got the data from a 1986 catalog. You could try a search on ebay for the RS part numbers. You can do a saved search and get a notification if one is listed.. The closest bit I can find is the Weller CT5 series for the W61 iron. e.g CT5 C6 3.2 mm Screwdriver Soldering Iron Tip RS stock no 176-6879. This will probably need modification to fit though.
