Ah, you want an HT... HA HA, though I do know of one "spare" floating around right now, though a rebuild. He wants WAY too much for it. He wants $4K, it's worth $2K tops.
As to III's, yeah, shouldn't be a drama, though the prices are getting nuts. Got a mate in Brisbane with maybe 30 III's - all with volley sights still, about 5 of them are ex-QP! (one came from Terry Lewis' collection, along with a Q^P I*).
I used to collect SMLE's madly - had 197 at one point, then got married...
Geoff, hence why I intend repainting it white with a Vixen decal
Maybe stencil it, "Telescope, Vixen, FL102S (refractor)"
