I need to reduce my hoard of spares, so to start, I have 2 pairs of Factory 748 barrels and h/c pistons including rings and gudgeon pins. One pair is brand new and one pair was taken from my refreshed 748RS engine when it was upgraded to an 853, that looks like it was only bench run so are very clean with the original honing marks clearly visible in the barrels. After checking with MR, the gudgeon pin size is common to all years and all models of the 748 so these could be an upgrade for your base/e/s or spares for your R/SP/SPS. Happy to provide pictures and discuss price but please don't confuse my need to reduce the amount of stuff I have with any willingness to give it away . Andy
