Swivel Housings HTC2373 & HRC2778

Dear All, I have 2x refurbished swivel housings numbered HRC2373 & HRC2778 bought in error last summer. Full numbers are as follows

HRC2373 [24 A 94 D] LEE SG6
HRC2376 [8 C 99] LEE SG6

I want to put these up for sale but can't find the lrworkshop/original part number. Can anyone help?

Thank you,
v8250

I think FTC5296 and FTC5297 (for RHD vehicles)
