Strand lamp base P 28 for Patt 23/123/223 etc.

I have just ordered a batch of direct replacement lamp bases to suit the Patt 23/123/ 223/45/264 Strand lights and they will cost under $20 each and this will make it economical to repair these older lights as currently a similar base costs $80 and then you have to re-drill holes to make it fit.Anyone who may be able to use these please contact me.
